Subject: [PATCH 0/3] allow zram to use zbud as underlying allocator
Date: Mon, 14 Sep 2015 15:49:01 +0200 [thread overview]
Message-ID: <20150914154901.92c5b7b24e15f04d8204de18@gmail.com> (raw)
While using ZRAM on a small RAM footprint devices, together with KSM, I ran into several occasions when moving pages from compressed swap back into the "normal" part of RAM caused significant latencies in system operation. By using zbud I lose in compression ratio but gain in determinism, lower latencies and lower fragmentation, so in the coming patches I tried to generalize what I've done to enable zbud for zram so far.
