Subject: tracing: Rename 'lockdep' event subsystem into 'lock'
X-Git-Tag: v2.6.33-rc1~48^2~288^2~20
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=67178767b936fb47a3a5e88097cff41ccbda7acb;p=platform%2Fkernel%2Flinux-3.10.git

tracing: Rename 'lockdep' event subsystem into 'lock'

Lockdep events subsystem gathers various locking related events
such as a request, release, contention or acquisition of a lock.

The name of this event subsystem is a bit of a misnomer since
these events are not quite related to lockdep but more generally
to locking, ie: these events are not reporting lock dependencies
or possible deadlock scenario but pure locking events.

Hence this rename.
