xfs: fix returned valued from xfs_defer_can_append

2026-03-06T08:30:07Z

xfs_defer_can_append returns a bool, it shouldn't be returning a NULL. Found by code inspection.

xfs: Remove redundant NULL check after __GFP_NOFAIL

2026-03-05T09:02:45Z

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

2026-02-25T12:58:50Z

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()

2026-02-25T12:58:49Z

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

2026-02-25T12:58:48Z

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.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28Z

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook
