xfs: annotate struct xfs_attr_list_context with __counted_by_ptr

2026-03-18T08:54:39+00:00

Add the `__counted_by_ptr` attribute to the `buffer` field of `struct xfs_attr_list_context`. This field is used to point to a buffer of size `bufsize`. The `buffer` field is assigned in: 1. `xfs_ioc_attr_list` in `fs/xfs/xfs_handle.c` 2. `xfs_xattr_list` in `fs/xfs/xfs_xattr.c` 3. `xfs_getparents` in `fs/xfs/xfs_handle.c` (implicitly initialized to NULL) In `xfs_ioc_attr_list`, `buffer` was assigned before `bufsize`. Reorder them to ensure `bufsize` is set before `buffer` is assigned, although no access happens between them. In `xfs_xattr_list`, `buffer` was assigned before `bufsize`. Reorder them to ensure `bufsize` is set before `buffer` is assigned. In `xfs_getparents`, `buffer` is NULL (from zero initialization) and remains NULL. `bufsize` is set to a non-zero value, but since `buffer` is NULL, no access occurs. In all cases, the pointer `buffer` is not accessed before `bufsize` is set. This patch was generated by CodeMender and reviewed by Bill Wendling. Tested by running xfstests.

xfs: Remove redundant NULL check after __GFP_NOFAIL

kzalloc() is called with __GFP_NOFAIL, so a NULL return is not expected. Drop the redundant !map check in xfs_dabuf_map(). Also switch the nirecs-sized allocation to kcalloc(). Signed-off-by: hongao Reviewed-by: Christoph Hellwig Signed-off-by: Carlos Maiolino

xfs: add static size checks for ioctl UABI

2026-02-25T12:58:50+00:00

The ioctl structures in libxfs/xfs_fs.h are missing static size checks. It is useful to have static size checks for these structures as adding new fields to them could cause issues (e.g. extra padding that may be inserted by the compiler). So add these checks to xfs/xfs_ondisk.h. Due to different padding/alignment requirements across different architectures, to avoid build failures, some structures are ommited from the size checks. For example, structures with "compat_" definitions in xfs/xfs_ioctl32.h are ommited. Signed-off-by: Wilfred Mallawa Reviewed-by: Christoph Hellwig Signed-off-by: Carlos Maiolino

xfs: Add a comment in xfs_log_sb()

2026-02-25T12:58:49+00:00

Add a comment explaining why the sb_frextents are updated outside the if (xfs_has_lazycount(mp) check even though it is a lazycounter. RT groups are supported only in v5 filesystems which always have lazycounter enabled - so putting it inside the if(xfs_has_lazycount(mp) check is redundant.

xfs: remove metafile inodes from the active inode stat

2026-02-25T12:58:48+00:00

The active inode (or active vnode until recently) stat can get much larger than expected on file systems with a lot of metafile inodes like zoned file systems on SMR hard disks with 10.000s of rtg rmap inodes. Remove all metafile inodes from the active counter to make it more useful to track actual workloads and add a separate counter for active metafile inodes. This fixes xfs/177 on SMR hard drives.
