Subject: [RFC 0/9] Reclaim during GFP_ATOMIC allocs
Date: Tue, 14 Aug 2007 08:30:21 -0700 [thread overview]
Message-ID: <20070814153021.446917377@sgi.com> (raw)
This is the extended version of the reclaim patchset. It enables reclaim from
clean file backed pages during GFP_ATOMIC allocs. A bit invasive since
may locks must now be taken with saving flags. But it works.
Tested by repeatedly allocating 12MB of memory from the timer interrupt.
