Subject: [PATCH v2 0/1] xfs: Fail remount with noattr2 on a v5 xfs with v4 enabled kernel.

This patch fixes an issue where remount with noattr2 doesn't fail explicitly
on v5 xfs with CONFIG_XFS_SUPPORT_V4=y. Details are there in the commit message
of the patch.

Related discussion in [1].

[v1] --> v2
 - Added another final verification with xfs_finish_flags() in xfs_fs_reconfigure()
   during remount.
