Subject: lib/lock: the last piece
X-Git-Tag: 2011.11.20-535097~33
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=08bcfff1fdc800988458e680d4cbc893ed042cb8;p=thirdparty%2Fopen-vm-tools.git

lib/lock: the last piece

This will put lib/lock such that the real-time checking
can be done while not changing the size of any structure.

This backs out changes to the point that we can go forward.
