description |
A patch upstream landed on 2011-12-6 that reduces the mmap_sem hold time, which is crucial
during OOM killer invocation. It would be very beneficial if this patch could get pulled into all supported arm precise kernels.
See http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=7178/1 for details on the patch. The upstream git commit is http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=8878a539ff19a43cf3729e7562cd528f490246ae
I have attached the raw patch as well for review. |
SRU JUSTIFICATION
=================
EFFECT
======
Reduce mmap_sem lock contention on arm while using java (see below)
FIX
===
see the attached patch
TEST
====
This commit has already been incorporated/tested in the armadaxp kernel and impacts
only the arm side of master, proposing for P/master (omap4 will get it via
rebase).
