2013-05-10[SCSI] sas: unify the pointlessly separated enums sas_dev_type and ↵James Bottomley20-144/+144
sas_device_type These enums have been separate since the dawn of SAS, mainly because the latter is a procotol only enum and the former includes additional state for libsas. The dichotomy causes endless confusion about which one you should use where and leads to pointless warnings like this: drivers/scsi/mvsas/mv_sas.c: In function 'mvs_update_phyinfo': drivers/scsi/mvsas/mv_sas.c:1162:34: warning: comparison between 'enum sas_device_type' and 'enum sas_dev_type' [-Wenum-compare] Fix by eliminating one of them.

2013-05-03[SCSI] sd: fix array cache flushing bug causing performance problemsJames Bottomley2-0/+21
Some arrays synchronize their full non volatile cache when the sd driver sends a SYNCHRONIZE CACHE command. Unfortunately, they can have Terrabytes of this and we send a SYNCHRONIZE CACHE for every barrier if an array reports it has a writeback cache. This leads to massive slowdowns on journalled filesystems. The fix is to allow userspace to turn off the writeback cache setting as a temporary measure (i.e. without doing the MODE SELECT to write it back to the device), so even though the device reported it has a writeback cache, the user, knowing that the cache is non volatile and all they care about is filesystem correctness, can turn that bit off in the kernel and avoid the performance ruinous (and safety irrelevant) SYNCHRONIZE CACHE commands. The way you do this is add a 'temporary' prefix when performing the usual cache setting operations, so echo temporary write through > /sys/class/scsi_disk/<disk>/cache_type Reported-by: Ric Wheeler <rwheeler@redhat.com> Cc: <stable@vger.kernel.org> Signed-off-by: James Bottomley <JBottomley@Parallels.com>

2013-05-03[SCSI] scsi_debug: fix logical block provisioning supportAkinobu Mita1-40/+41
provisioning map (map_storep) is a bitmap accessed by bitops. So the allocation size should be a multiple of sizeof(unsigned long) and also the bitmap should be cleared by using bitmap_clear() instead of memset(). Otherwise it will cause problem on big-endian architecture if the number of bits is not a multiple of BITS_PER_LONG. I tried testing the logical block provisioning support in scsi_debug, but it didn't work as I expected. For example, load scsi_debug module with UNMAP command supported and fill the storage with random data. # modprobe scsi_debug lbpu=1 # dd if=/dev/urandom of=/dev/sdb Then, try to unmap LBA 0, but Get LBA status reports: # sg_unmap --lba=0 --num=1 /dev/sdb # sg_get_lba_status --lba=0 /dev/sdb descriptor LBA: 0x0000000000000000 blocks: 16384 mapped This is unexpected result. Because UNMAP command to LBA 0 finished without any errors, but Get LBA status shows that LBA 0 is still mapped. This problem is due to the wrong translation between LBA and index of provisioning map. Fix it by using correct translation functions.

2013-05-03[SCSI] scsi_debug: clear correct memory region when LBPRZ is enabledAkinobu Mita1-2/+3
The function unmap_region() clears memory region specified as the logical block address and the number of logical blocks in ramdisk storage (fake_storep) if lbpu and lbprz module parameters are enabled. In the while loop of unmap_region(), it advances optimal unmap granularity in logical blocks. But it only clears one logical block at LBA 'block' per loop iteration. And furthermore, the 'block' is not pointing to a logical block address which should be cleared, it is a index of probisioning map (map_storep).

scsi_debug_unmap_alignment scsi_debug prohibits setting scsi_debug_unmap_alignment to be greater than scsi_debug_unmap_granularity. But setting them to be the same value is not prohibited. In this case, the only difference with scsi_debug_unmap_alignment == 0 is the logical blocks from 0 to scsi_debug_unmap_alignment - 1 cannot be unmapped. But the difference is not properly handled in the current code. So this prohibits such unusual setting. Signed-off-by: Akinobu Mita <akinobu.mita@gmail.com> Acked-by: Martin K.

2013-05-03[SCSI] scsi_debug: call map_region() and unmap_region() only when neededAkinobu Mita1-3/+3
If the logical block provisioning is not enabled, map_region() and unmap_region() have no effect and they don't need to be called. So this makes map_region() and unmap_region() to be called only when scsi_debug_lbp() returns true, i.e. logical block provisioning is enabled. While I'm at it, this also removes meaningless non-zero check for scsi_debug_unmap_granularity. Because scsi_debug_unmap_granularity cannot be zero with usual setting: scsi_debug_unmap_granularity is 1 by default, and it can be changed to zero with explicit module parameter setting only when the logical block provisioning is disabled. But it is only meaningful module parameter when the logical block provisioning is enabled. Signed-off-by: Akinobu Mita <akinobu.mita@gmail.com> Acked-by: Martin K.

Hopefully correctly resolved. * tag 'virtio-next-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux: (57 commits) caif_virtio: Remove bouncing email addresses lguest: improve code readability in lg_cpu_start. virtio-net: fill only rx queues which are being used lguest: map Switcher below fixmap. lguest: cache last cpu we ran on. lguest: map Switcher text whenever we allocate a new pagetable. lguest: don't share Switcher PTE pages between guests. lguest: expost switcher_pages array (as lg_switcher_pages). lguest: extract shadow PTE walking / allocating. lguest: make check_gpte et. al return bool. lguest: assume Switcher text is a single page. lguest: rename switcher_page to switcher_pages. lguest: remove RESERVE_MEM constant. lguest: check vaddr not pgd for Switcher protection. lguest: prepare to make SWITCHER_ADDR a variable. virtio: console: replace EMFILE with EBUSY for already-open port virtio-scsi: reset virtqueue affinity when doing cpu hotplug virtio-scsi: introduce multiqueue support virtio-scsi: push vq lock/unlock into virtscsi_vq_done virtio-scsi: pass struct virtio_scsi to virtqueue completion function ...
