New Revision: 304950
URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=304950
Log:
Change mutex tracking so that it only consumes memory in the core mutex object when it's actually being used.
This reduces the overall size of a mutex which was 3016 bytes before this back
down to 216 bytes (this is on 64-bit Linux with a glibc-implemented mutex).
The exactness of the numbers here may vary slightly based upon how mutexes are
implemented on a platform, but the long and short of it is that prior to this
commit, chan_iax2 held down 98MB of memory on a 64-bit system for nothing more
than a table of 32767 locks. After this commit, the same table occupies a mere
7MB of memory.
(closes issue #18194)
