[PATCH 0/4] btrfs: stop duplicating VFS code for subvolume/snapshot dentry

[fdmanana@kernel.org]

From: Filipe Manana <fdmanana@suse.com>

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.

Filipe Manana (4):
  fs: export may_delete() as may_delete_dentry()
  fs: export may_create() as may_create_dentry()
  btrfs: use may_delete_dentry() in btrfs_ioctl_snap_destroy()
  btrfs: use may_create_dentry() in btrfs_mksubvol()
