From ab7bb61092308e83130b8d15725aee1672991d65 Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Wed, 29 Jul 2015 11:51:01 +1000 Subject: [PATCH] xfs: xfs_bunmapi() does not need XFS_BMAPI_METADATA flag xfs_bunmapi() doesn't care what type of extent is being freed and does not look at the XFS_BMAPI_METADATA flag at all. As such we can remove the XFS_BMAPI_METADATA from all callers that use it.
