Subject: kmemleak: Allow kmemleak metadata allocations to fail
X-Git-Tag: v2.6.38-rc3~17^2
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6ae4bd1f0bc479984f30061b5e5116060c24a267;p=pandora-kernel.git

kmemleak: Allow kmemleak metadata allocations to fail

This patch adds __GFP_NORETRY and __GFP_NOMEMALLOC flags to the kmemleak
metadata allocations so that it has a smaller effect on the users of the
kernel slab allocator. Since kmemleak allocations can now fail more
often, this patch also reduces the verbosity by passing __GFP_NOWARN and
not dumping the stack trace when a kmemleak allocation fails.
