Btrfs: add missing inode version, ctime and mtime updates when punching hole
If the range for which we are punching a hole covers only part of a page, we end up updating the inode item but we skip the update of the inode's iversion, mtime and ctime. Fix that by ensuring we update those properties of the inode. A patch for fstests test case generic/059 that tests this as been sent along with this fix. Fixes: 2aaa66558172b0 ("Btrfs: add hole punching") Fixes: e8c1c76e804b18 ("Btrfs: add missing inode update when punching hole") CC: stable@vger.kernel.org # 4.4+ Signed-off-by: Filipe Manana <fdmanana@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
