Merge patch series "btrfs: stop duplicating VFS code for subvolume/snapshot dentry"
Filipe Manana <fdmanana@suse.com> says:
Currently btrfs has copies of two unexported functions from fs/namei.c
used in the snapshot/subvolume creation and deletion. This patchset
exports those functions and makes btrfs use them, to avoid duplication
and the burden of keeping the copies up to date.
* patches from https://patch.msgid.link/cover.1768307858.git.fdmanana@suse.com:
btrfs: use may_create_dentry() in btrfs_mksubvol()
btrfs: use may_delete_dentry() in btrfs_ioctl_snap_destroy()
fs: export may_create() as may_create_dentry()
fs: export may_delete() as may_delete_dentry()
