There are currently 2 ways to create a set of sysfs files for a kobj_type, through the default_attrs field, and the default_groups field.

2021-01-22xfs: Introduce error injection to allocate only minlen size extents for filesChandan Babu R
This commit adds XFS_ERRTAG_BMAP_ALLOC_MINLEN_EXTENT error tag which helps userspace test programs to get xfs_bmap_btalloc() to always allocate minlen sized extents. This is required for test programs which need a guarantee that minlen extents allocated for a file do not get merged with their existing neighbours in the inode's BMBT. "Inode fork extent overflow check" for Directories, Xattrs and extension of realtime inodes need this since the file offset at which the extents are being allocated cannot be explicitly controlled from userspace. One way to use this error tag is to, 1. Consume all of the free space by sequentially writing to a file. 2. Punch alternate blocks of the file. This causes CNTBT to contain sufficient number of one block sized extent records. 3. Inject XFS_ERRTAG_BMAP_ALLOC_MINLEN_EXTENT error tag. After step 3, xfs_bmap_btalloc() will issue space allocation requests for minlen sized extents only. ENOSPC error code is returned to userspace when there aren't any "one block sized" extents left in any of the AGs. Reviewed-by: Darrick J.

2019-02-11xfs: cache unlinked pointers in an rhashtableDarrick J. Wong
Use a rhashtable to cache the unlinked list incore. This should speed up unlinked processing considerably when there are a lot of inodes on the unlinked list because iunlink_remove no longer has to traverse an entire bucket list to find which inode points to the one being removed. The incore list structure records "X.next_unlinked = Y" relations, with the rhashtable using Y to index the records. This makes finding the inode X that points to a inode Y very quick. If our cache fails to find anything we can always fall back on the old method. FWIW this drastically reduces the amount of time it takes to remove inodes from the unlinked list. I wrote a program to open a lot of O_TMPFILE files and then close them in the same order, which takes a very long time if we have to traverse the unlinked lists.

2017-10-26xfs: buffer lru reference count error injection tagBrian Foster
XFS uses a fixed reference count for certain types of buffers in the internal LRU cache. These reference counts dictate how aggressively certain buffers are reclaimed vs. others. While the reference counts implements priority across different buffer types, all buffers (other than uncached buffers) are typically cached for at least one reclaim cycle. We've had at least one bug recently that has been hidden by a released buffer sitting around in the LRU. Users hitting the problem were able to reproduce under enough memory pressure to cause aggressive reclaim in a particular window of time. To support future xfstests cases, add an error injection tag to hardcode the buffer reference count to zero. When enabled, this bypasses caching of associated buffers and facilitates test cases that depend on this behavior. Signed-off-by: Brian Foster <bfoster@redhat.com> Reviewed-by: Darrick J.

2017-08-22xfs: add log item pinning error injection tagBrian Foster
Add an error injection tag to force log items in the AIL to the pinned state. This option can be used by test infrastructure to induce head behind tail conditions. Specifically, this is intended to be used by xfstests to reproduce log recovery problems after failed/corrupted log writes overwrite the last good tail LSN in the log. When enabled, AIL push attempts see log items in the AIL in the pinned state. This stalls metadata writeback and thus prevents the current tail of the log from moving forward. When disabled, subsequent AIL pushes observe the log items in their appropriate state and filesystem operation continues as normal.
