Subject: lockdep:  Decrease lockdep backtrace skip by 1
X-Git-Tag: v0.56~52
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=a7de975d9344621201a09b03453682cc7c798892;p=ceph.git

lockdep:  Decrease lockdep backtrace skip by 1

Skipping the top 4 (it starts at 0) calls in the
backtrace actually skips the call that does the lock.
Skip 3 instead.
