Subject: lib/lock: continue putting code back
X-Git-Tag: 2011.11.20-535097~37
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=4dfa067b5280dffb6180b0f78d68e69ce1e3d362;p=thirdparty%2Fopen-vm-tools.git

lib/lock: continue putting code back

I'm working my way towards reintegrating the run-time
checking version which was code-read.
