Description David Teigland 2007-10-30 18:34:20 UTC 
Description of problem:

"If the castaddr passed to the userland API is NULL then don't overwrite the
existing castparam. This allows a different thread to cancel a lock request and
the CANCEL AST gets delivered to the original thread.

bz#306391 (for RHEL4) refers." -- pjc
