2023-04-13f2fs: fix to check readonly condition correctlyChao Yu1-1/+1
With below case, it can mount multi-device image w/ rw option, however one of secondary device is set as ro, later update will cause panic, so let's introduce f2fs_dev_is_readonly(), and check multi-devices rw status in f2fs_remount() w/ it in order to avoid such inconsistent mount status. mkfs.f2fs -c /dev/zram1 /dev/zram0 -f blockdev --setro /dev/zram1 mount -t f2fs dev/zram0 /mnt/f2fs mount: /mnt/f2fs: WARNING: source write-protected, mounted read-only. mount -t f2fs -o remount,rw mnt/f2fs dd if=/dev/zero of=/mnt/f2fs/file bs=1M count=8192 kernel BUG at fs/f2fs/inline.c:258!

2023-04-10f2fs: use f2fs_hw_is_readonly() instead of bdev_read_only()Chao Yu1-2/+2
f2fs has supported multi-device feature, to check devices' rw status, it should use f2fs_hw_is_readonly() rather than bdev_read_only(), fix it. Meanwhile, it removes f2fs_hw_is_readonly() check condition in: - f2fs_write_checkpoint() - f2fs_convert_inline_inode() As it has checked f2fs_readonly() condition, and if f2fs' devices were readonly, f2fs_readonly() must be true.

2022-12-13f2fs: add block_age-based extent cacheJaegeuk Kim1-0/+14
This patch introduces a runtime hot/cold data separation method for f2fs, in order to improve the accuracy for data temperature classification, reduce the garbage collection overhead after long-term data updates. Enhanced hot/cold data separation can record data block update frequency as "age" of the extent per inode, and take use of the age info to indicate better temperature type for data block allocation: - It records total data blocks allocated since mount; - When file extent has been updated, it calculate the count of data blocks allocated since last update as the age of the extent; - Before the data block allocated, it searches for the age info and chooses the suitable segment for allocation. Test and result: - Prepare: create about 30000 files * 3% for cold files (with cold file extension like .apk, from 3M to 10M) * 50% for warm files (with random file extension like .FcDxq, from 1K to 4M) * 47% for hot files (with hot file extension like .db, from 1K to 256K) - create(5%)/random update(90%)/delete(5%) the files * total write amount is about 70G * fsync will be called for .db files, and buffered write will be used for other files The storage of test device is large enough(128G) so that it will not switch to SSR mode during the test. Benefit: dirty segment count increment reduce about 14% - before: Dirty +21110 - after: Dirty +18286 Signed-off-by: qixiaoyu1 <qixiaoyu1@xiaomi.com> Signed-off-by: xiongping1 <xiongping1@xiaomi.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

Usage: a) echo 262144 > /sys/fs/f2fs/<dev>/inject_type or b) mount -o fault_type=262144 <dev> <mountpoint> Signed-off-by: Chao Yu <chao@kernel.org> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

request_queues are a block layer implementation detail that should not leak into file systems. Change the fscrypt inline crypto code to retrieve block devices instead of request_queues from the file system. As part of that, clean up the interaction with multi-device file systems by returning both the number of devices and the actual device array in a single method call.

2022-09-13f2fs: increase the limit for reserve_rootJaegeuk Kim1-2/+2
This patch increases the threshold that limits the reserved root space from 0.2% to 12.5% by using simple shift operation. Typically Android sets 128MB, but if the storage capacity is 32GB, 0.2% which is around 64MB becomes too small. Let's relax it.

2022-07-04mm: shrinkers: provide shrinkers with namesRoman Gushchin1-1/+1
Currently shrinkers are anonymous objects. For debugging purposes they can be identified by count/scan function names, but it's not always useful: e.g. for superblock's shrinkers it's nice to have at least an idea of to which superblock the shrinker belongs. This commit adds names to shrinkers. register_shrinker() and prealloc_shrinker() functions are extended to take a format and arguments to master a name. In some cases it's not possible to determine a good name at the time when a shrinker is allocated. For such cases shrinker_debugfs_rename() is provided. The expected format is: <subsystem>-<shrinker_type>[:<instance>]-<id> For some shrinkers an instance can be encoded as (MAJOR:MINOR) pair. After this change the shrinker debugfs directory looks like: $ cd /sys/kernel/debug/shrinker/ $ ls dquota-cache-16 sb-devpts-28 sb-proc-47 sb-tmpfs-42 mm-shadow-18 sb-devtmpfs-5 sb-proc-48 sb-tmpfs-43 mm-zspool:zram0-34 sb-hugetlbfs-17 sb-pstore-31 sb-tmpfs-44 rcu-kfree-0 sb-hugetlbfs-33 sb-rootfs-2 sb-tmpfs-49 sb-aio-20 sb-iomem-12 sb-securityfs-6 sb-tracefs-13 sb-anon_inodefs-15 sb-mqueue-21 sb-selinuxfs-22 sb-xfs:vda1-36 sb-bdev-3 sb-nsfs-4 sb-sockfs-8 sb-zsmalloc-19 sb-bpf-32 sb-pipefs-14 sb-sysfs-26 thp-deferred_split-10 sb-btrfs:vda2-24 sb-proc-25 sb-tmpfs-1 thp-zero-9 sb-cgroup2-30 sb-proc-39 sb-tmpfs-27 xfs-buf:vda1-37 sb-configfs-23 sb-proc-41 sb-tmpfs-29 xfs-inodegc:vda1-38 sb-dax-11 sb-proc-45 sb-tmpfs-35 sb-debugfs-7 sb-proc-46 sb-tmpfs-40 [roman.gushchin@linux.dev: fix build warnings] Link: https://lkml.kernel.org/r/Yr+ZTnLb9lJk6fJO@castle Reported-by: kernel test robot <lkp@intel.com> Link: https://lkml.kernel.org/r/20220601032227.4076670-4-roman.gushchin@linux.dev Signed-off-by: Roman Gushchin <roman.gushchin@linux.dev> Cc: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Cc: Dave Chinner <dchinner@redhat.com> Cc: Hillf Danton <hdanton@sina.com> Cc: Kent Overstreet <kent.overstreet@gmail.com> Cc: Muchun Song <songmuchun@bytedance.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
