Subject: ocfs2: Convert ocfs2 over to unlocked_ioctl
X-Git-Tag: v2.6.26-rc1~1143^2~5
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c9ec14884d69a303eef4faae42bd3c4e25b19941;p=platform%2Fupstream%2Fkernel-adaptation-pc.git

ocfs2: Convert ocfs2 over to unlocked_ioctl

As far as I can see there is nothing in ocfs2_ioctl that requires the BKL,
so use unlocked_ioctl
