Subject: binder: Remove unused binder lock events
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a594dec7607744a8f877c8516c73a7728a7b66e3;p=thirdparty%2Fkernel%2Fstable.git

binder: Remove unused binder lock events

Trace events can take up to 5K each when they are defined, regardless if
they are used or not. The binder lock events: binder_lock, binder_locked
and binder_unlock are no longer used.

Remove them.
