[PATCH 079/115] xfs: make the reserved block permission flag explicit in xfs_attr_set

["Darrick J. Wong" <djwong@xxxxxxxxxx>]

From: Darrick J. Wong <djwong@xxxxxxxxxx>

Source kernel commit: bf61c36a45d4c215994699a7a06a00c58d22e8a2

Make the use of reserved blocks an explicit parameter to xfs_attr_set.
Userspace setting XFS_ATTR_ROOT attrs should continue to be able to use
it, but for online repairs we can back out and therefore do not care.
