Subject: [PATCH] xfs: fix I_DONTCACHE
Git-commit: f38a032b165d812b0ba8378a5cd237c0888ff65f
Patch-mainline: v5.15-rc1
References: git-fixes
Yup, the VFS hoist broke it, and nobody noticed. Bulkstat workloads
make it clear that it doesn't work as it should.
Fixes: dae2f8ed7992 ("fs: Lift XFS_IDONTCACHE to the VFS layer")
