-Required properties:
-- compatible : Should be "smsc,lan<model>", "smsc,lan9115"
-- reg : Address and length of the io space for SMSC LAN
-- interrupts : one or two interrupt specifiers
- - The first interrupt is the SMSC LAN interrupt line
- - The second interrupt (if present) is the PME (power
- management event) interrupt that is able to wake up the host
- system with a 50ms pulse on network activity
-- phy-mode : See ethernet.txt file in the same directory
-
-Optional properties:
-- reg-shift : Specify the quantity to shift the register offsets by
-- reg-io-width : Specify the size (in bytes) of the IO accesses that
- should be performed on the device. Valid value for SMSC LAN is
- 2 or 4. If it's omitted or invalid, the size would be 2.
-- smsc,irq-active-high : Indicates the IRQ polarity is active-high
-- smsc,irq-push-pull : Indicates the IRQ type is push-pull
-- smsc,force-internal-phy : Forces SMSC LAN controller to use
- internal PHY
-- smsc,force-external-phy : Forces SMSC LAN controller to use

Linux Kernel TIPC
=================
-TIPC (Transparent Inter Process Communication) is a protocol that is
-specially designed for intra-cluster communication.
+Introduction
+============
-For more information about TIPC, see http://tipc.sourceforge.net.
+TIPC (Transparent Inter Process Communication) is a protocol that is specially
+designed for intra-cluster communication. It can be configured to transmit
+messages either on UDP or directly across Ethernet. Message delivery is
+sequence guaranteed, loss free and flow controlled. Latency times are shorter
+than with any other known protocol, while maximal throughput is comparable to
+that of TCP.
+
+TIPC Features
+-------------
+
+- Cluster wide IPC service
+
+ Have you ever wished you had the convenience of Unix Domain Sockets even when
+ transmitting data between cluster nodes? Where you yourself determine the
+ addresses you want to bind to and use? Where you don't have to perform DNS
+ lookups and worry about IP addresses? Where you don't have to start timers
+ to monitor the continuous existence of peer sockets? And yet without the
+ downsides of that socket type, such as the risk of lingering inodes?
+
+ Welcome to the Transparent Inter Process Communication service, TIPC in short,
+ which gives you all of this, and a lot more.
+
+- Service Addressing
+
+ A fundamental concept in TIPC is that of Service Addressing which makes it
+ possible for a programmer to chose his own address, bind it to a server
+ socket and let client programs use only that address for sending messages.
+
+- Service Tracking
+
+ A client wanting to wait for the availability of a server, uses the Service
+ Tracking mechanism to subscribe for binding and unbinding/close events for
+ sockets with the associated service address.
+
+ The service tracking mechanism can also be used for Cluster Topology Tracking,
+ i.e., subscribing for availability/non-availability of cluster nodes.
+
+ Likewise, the service tracking mechanism can be used for Cluster Connectivity
+ Tracking, i.e., subscribing for up/down events for individual links between
+ cluster nodes.
+
+- Transmission Modes
+
+ Using a service address, a client can send datagram messages to a server socket.
+
+ Using the same address type, it can establish a connection towards an accepting
+ server socket.
+
+ It can also use a service address to create and join a Communication Group,
+ which is the TIPC manifestation of a brokerless message bus.
+
+ Multicast with very good performance and scalability is available both in
+ datagram mode and in communication group mode.
+
+- Inter Node Links
+
+ Communication between any two nodes in a cluster is maintained by one or two
+ Inter Node Links, which both guarantee data traffic integrity and monitor
+ the peer node's availability.
+
+- Cluster Scalability
+
+ By applying the Overlapping Ring Monitoring algorithm on the inter node links
+ it is possible to scale TIPC clusters up to 1000 nodes with a maintained
+ neighbor failure discovery time of 1-2 seconds. For smaller clusters this
+ time can be made much shorter.
+
+- Neighbor Discovery
+
+ Neighbor Node Discovery in the cluster is done by Ethernet broadcast or UDP
+ multicast, when any of those services are available. If not, configured peer
+ IP addresses can be used.
+
+- Configuration
+
+ When running TIPC in single node mode no configuration whatsoever is needed.
+ When running in cluster mode TIPC must as a minimum be given a node address
+ (before Linux 4.17) and told which interface to attach to. The "tipc"
+ configuration tool makes is possible to add and maintain many more
+ configuration parameters.
+
+- Performance
+
+ TIPC message transfer latency times are better than in any other known protocol.
+ Maximal byte throughput for inter-node connections is still somewhat lower than
+ for TCP, while they are superior for intra-node and inter-container throughput
+ on the same host.
+
+- Language Support
+
+ The TIPC user API has support for C, Python, Perl, Ruby, D and Go.

/*
- * If force is CHUNK_ALLOC_FORCE:
+ * Chunk allocation is done in 2 phases:
+ *
+ * 1) Phase 1 - through btrfs_chunk_alloc() we allocate device extents for
+ * the chunk, the chunk mapping, create its block group and add the items
+ * that belong in the chunk btree to it - more specifically, we need to
+ * update device items in the chunk btree and add a new chunk item to it.
+ *
+ * 2) Phase 2 - through btrfs_create_pending_block_groups(), we add the block
+ * group item to the extent btree and the device extent items to the devices
+ * btree.
+ *
+ * This is done to prevent deadlocks. For example when COWing a node from the
+ * extent btree we are holding a write lock on the node's parent and if we
+ * trigger chunk allocation and attempted to insert the new block group item
+ * in the extent btree right way, we could deadlock because the path for the
+ * insertion can include that parent node. At first glance it seems impossible
+ * to trigger chunk allocation after starting a transaction since tasks should
+ * reserve enough transaction units (metadata space), however while that is true
+ * most of the time, chunk allocation may still be triggered for several reasons:
+ *
+ * 1) When reserving metadata, we check if there is enough free space in the
+ * metadata space_info and therefore don't trigger allocation of a new chunk.
+ * However later when the task actually tries to COW an extent buffer from
+ * the extent btree or from the device btree for example, it is forced to
+ * allocate a new block group (chunk) because the only one that had enough
+ * free space was just turned to RO mode by a running scrub for example (or
+ * device replace, block group reclaim thread, etc), so we can not use it
+ * for allocating an extent and end up being forced to allocate a new one;
+ *
+ * 2) Because we only check that the metadata space_info has enough free bytes,
+ * we end up not allocating a new metadata chunk in that case. However if
+ * the filesystem was mounted in degraded mode, none of the existing block
+ * groups might be suitable for extent allocation due to their incompatible
+ * profile (for e.g. mounting a 2 devices filesystem, where all block groups
+ * use a RAID1 profile, in degraded mode using a single device). In this case
+ * when the task attempts to COW some extent buffer of the extent btree for
+ * example, it will trigger allocation of a new metadata block group with a
+ * suitable profile (SINGLE profile in the example of the degraded mount of
+ * the RAID1 filesystem);
+ *
+ * 3) The task has reserved enough transaction units / metadata space, but when
+ * it attempts to COW an extent buffer from the extent or device btree for
+ * example, it does not find any free extent in any metadata block group,
+ * therefore forced to try to allocate a new metadata block group.
+ * This is because some other task allocated all available extents in the
+ * meanwhile - this typically happens with tasks that don't reserve space
+ * properly, either intentionally or as a bug. One example where this is
+ * done intentionally is fsync, as it does not reserve any transaction units
+ * and ends up allocating a variable number of metadata extents for log
+ * tree extent buffers.
+ *
+ * We also need this 2 phases setup when adding a device to a filesystem with
+ * a seed device - we must create new metadata and system chunks without adding
+ * any of the block group items to the chunk, extent and device btrees. If we
+ * did not do it this way, we would get ENOSPC when attempting to update those
+ * btrees, since all the chunks from the seed device are read-only.
+ *
+ * Phase 1 does the updates and insertions to the chunk btree because if we had
+ * it done in phase 2 and have a thundering herd of tasks allocating chunks in
+ * parallel, we risk having too many system chunks allocated by many tasks if
+ * many tasks reach phase 1 without the previous ones completing phase 2. In the
+ * extreme case this leads to exhaustion of the system chunk array in the
+ * superblock. This is easier to trigger if using a btree node/leaf size of 64K
+ * and with RAID filesystems (so we have more device items in the chunk btree).
+ * This has happened before and commit eafa4fd0ad0607 ("btrfs: fix exhaustion of
+ * the system chunk array due to concurrent allocations") provides more details.
+ *
+ * For allocation of system chunks, we defer the updates and insertions into the
+ * chunk btree to phase 2. This is to prevent deadlocks on extent buffers because
+ * if the chunk allocation is triggered while COWing an extent buffer of the
+ * chunk btree, we are holding a lock on the parent of that extent buffer and
+ * doing the chunk btree updates and insertions can require locking that parent.
+ * This is for the very few and rare cases where we update the chunk btree that
+ * are not chunk allocation or chunk removal: adding a device, removing a device
+ * or resizing a device.
+ *
+ * The reservation of system space, done through check_system_chunk(), as well
+ * as all the updates and insertions into the chunk btree must be done while
+ * holding fs_info->chunk_mutex. This is important to guarantee that while COWing
+ * an extent buffer from the chunks btree we never trigger allocation of a new
+ * system chunk, which would result in a deadlock (trying to lock twice an
+ * extent buffer of the chunk btree, first time before triggering the chunk
+ * allocation and the second time during chunk allocation while attempting to
+ * update the chunks btree). The system chunk array is also updated while holding
+ * that mutex. The same logic applies to removing chunks - we must reserve system
+ * space, update the chunk btree and the system chunk array in the superblock
+ * while holding fs_info->chunk_mutex.
+ *
