Subject: ***** SUSPECTED SPAM ***** [RFD 03/17] xfs: move inode chunk allocation into a workqueue
Date: Mon, 12 Aug 2013 23:19:53 +1000	[thread overview]
Message-ID: <1376313607-28133-4-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 allocation has been separated from free inode allocation,
we no longer need to do it in-line with the high level operation that requires
a free inode. As such, we can move inode chunk allocation into a workqueue and
trigger it to run asynchronously.

The inode allocation ticket will need to block the foreground operation if there
aren't sufficent free inodes available. It also needs to kick the inode
chunk allocation worker into action to ensure that free inodes will become
available in the not-to-distant future and wait for free inodes become
available.
