Subject: Re: ext4 deep stack with mark_page_dirty reclaim
Date: Mon, 14 Mar 2011 18:46:45 -0400	[thread overview]
Message-ID: <20110314224645.GA20348@infradead.org> (raw)

Direct reclaim (in the cgroup variant) at it's work.  We had a couple of
flamewars on this before, but this trivial example with reclaim from
the most simple case (swap space) shows that we really should never
reclaim from memory allocation callers for stack usage reasons.
