Author: bz Date: Sat Mar 27 17:54:44 2010 New Revision: 205764 URL: http://svn.freebsd.org/changeset/base/205764 Log: MFC r205626: Print the pointer to the lock with the panic message. The previous panic: rw lock not unlocked was not really helpful for debugging. Now one can at least call show lock <ptr> form ddb to learn more about the lock.
