Subject: Possible stable fix for decompressor speed
Date: Tue, 28 Jan 2014 16:14:28 +0000 [thread overview]
Message-ID: <20140128161428.GO11841@sirena.org.uk> (raw)

The changes in patch 1431574a1c4c (lib/decompressors: fix "no limit"
output buffer length) avoid doing decompression a byte at a time when
decompressing into high physical addresses using a small, well isolated
change. The patch can give a very noticable improvement in kernel boot
times on affected systems, for example with one ARM system this reduces
the total time to boot the kernel by more than a third.
Would you consider this patch for stable? It doesn't quite fit within
the criteria but you've indicated in the past that such isolated and
well supported changs can be acceptable anyway. If it's not OK for
stable it seems like it should be a good candidate for LTSI.
