Subject: [RFC][PATCH 0/2] optimise unlock_page / end_page_writeback
Date: Wed, 2 Nov 2016 18:03:44 +1100 [thread overview]
Message-ID: <20161102070346.12489-1-npiggin@gmail.com> (raw)
Hi,
There doesn't seem to be much more discussion about this, so let's
kick it along a bit. I tried to reclaim a page flag because I can't
bring myself to ifdef it to 64-bit only, but otherwise the patches
don't depend on each other at all.
Thanks,
Nick
