2005-08-26[PATCH] IB: fix use-after-free in user verbs cleanupRoland Dreier1-1/+2

2005-07-28[PATCH] [IB/cm]: Correct CM port redirect reject codesRoland Dreier1-1/+2
Reject code 24 is port and CM redirection, not just port redirection. Port redirection alone is code 25. Therefore we should rename code 24 to IB_CM_REJ_PORT_CM_REDIRECT and use IB_CM_REJ_PORT_REDIRECT for code 25. Signed-off-by: Roland Dreier <rolandd@cisco.com>
