Subject: ***** SUSPECTED SPAM ***** [RFD 08/17] xfs: inode chunk freeing in the background
Date: Mon, 12 Aug 2013 23:19:58 +1000	[thread overview]
Message-ID: <1376313607-28133-9-git-send-email-david@fromorbit.com> (raw)
In-Reply-To: <1376313607-28133-1-git-send-email-david@fromorbit.com>

From: Dave Chinner <dchinner@redhat.com>

Now that inode chunk freeing has been separated from freeing indivdiual inodes
we no longer need to do it in-line with the high level unlink inode operation.
As such, we can move inode chunk freeing into a workqueue and trigger it to run
asynchronously.

Moving the chunk freeing to the background allows us to delay the decision to
free the inode chunk and further optimise inode chunk freeing according to the
current workload.
