This is bad news, since the underlying linked list data structures could change during the msleep(). I haven't yet gotten to the point of coming up with a fix. Until then, I would recommend avoiding setting vfs.nfsd.enable_locallocks to 1. --=20 You are receiving this mail because: You are the assignee for the bug.=
