Subject: [PATCH 2/2] writeback, xfs: call dirty_inode() with I_DIRTY_TIME_EXPIRED when appropriate
Date: Thu, 19 Mar 2020 22:52:55 -0400	[thread overview]
Message-ID: <20200320025255.1705972-2-tytso@mit.edu> (raw)
In-Reply-To: <20200320025255.1705972-1-tytso@mit.edu>

Use the flag I_DIRTY_TIME_EXPIRED passed to dirty_inode() to signal to
the file system that it is time to flush the inode's timestamps to
stable storage.
