Subject: [PATCH 4.13 37/52] xfs: open-code xfs_buf_item_dirty()

4.13-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Brian Foster <bfoster@...hat.com>

commit a4f6cf6b2b6b60ec2a05a33a32e65caa4149aa2b upstream.

It checks a single flag and has one caller. It probably isn't worth
its own function.
