From 075529b5e1ffa8c9864d23930b71b5306a13d9f8 Mon Sep 17 00:00:00 2001 From: David Teigland Date: Wed, 13 Dec 2006 10:40:26 -0600 Subject: [DLM] fix lost flags in stub replies When the dlm fakes an unlock/cancel reply from a failed node using a stub message struct, it wasn't setting the flags in the stub message. So, in the process of receiving the fake message the lkb flags would be updated and cleared from the zero flags in the message. The problem observed in tests was the loss of the USER flag which caused the dlm to think a user lock was a kernel lock and subsequently fail an assertion checking the validity of the ast/callback field.
