I just wanted to see what (if any) effect it has on Alan's tests. (In the past, I've found that almost random changes can help identify a problem, like my suggestion to get rid of "nomsyncafterwrite".) If the patch happens to help with Alan's test case, then we need to figure out what needs to be done to fix it. W.r.t. ncl_writebp(), I'll take a look. This is all very old code cribbed from the old NFS client and not written by me. --=20 You are receiving this mail because: You are the assignee for the bug.=
