Subject: [Cluster-devel] [PATCH] gfs2: use __vmalloc GFP_NOFS for fs-related allocations.
Date: Sun, 1 Feb 2015 22:59:54 -0500 [thread overview]
Message-ID: <1422849594-15677-1-git-send-email-green@linuxhacker.ru> (raw)
From: Oleg Drokin <green@linuxhacker.ru>
leaf_dealloc uses vzalloc as a fallback to kzalloc(GFP_NOFS), so
it clearly does not want any shrinker activity within the fs itself.
convert vzalloc into __vmalloc(GFP_NOFS|__GFP_ZERO) to better achieve
this goal.
