[dahdi-commits] fjoe: freebsd/trunk r8795 - /freebsd/trunk/include/dahdi/compat/bsd.h

[SVN commits to the DAHDI project]

Author: fjoe
Date: Sun Jun 20 13:23:20 2010
New Revision: 8795

URL: http://svnview.digium.com/svn/dahdi?view=rev&rev=8795
Log:
Initialize rwlocks (that are actually sx locks) with SX_NOADAPTIVE, so they spin
instead of sleeping: dahdi_receive() calls process_masterspan() that uses
rwlocks and dahdi_receive() can be called from interrupt filter.
