Date: Thu, 03 Mar 2005 16:35:00 -0000 [thread overview] Message-ID: <20050303163520.31764.qmail@sourceware.org> (raw) CVSROOT: /cvs/cluster Module name: cluster Branch: RHEL4 Changes by: bmarzins@sourceware.org 2005-03-03 16:35:20 Modified files: gfs-kernel/src/gfs: incore.h log.h ops_fstype.c Log message: Fixed 146672. While it is still possible to see this bug, the problem that I saw every time it happened to me was that the process in gfs_log_dump() got starved waiting for the sd_log_lock semaphore. This fix changes sd_log_lock into a rw_semaphore, and uses down_write and up_write instead of down and up. read write semaphores are totally fair, so gfs_log_dump() can't get starved Patches: http://sources.redhat.com/cgi-bin/cvsweb.cgi/cluster/gfs-kernel/src/gfs/incore.h.diff?cvsroot=cluster&only_with_tag=RHEL4&r1=1.17&r2=1.17.2.1 http://sources.redhat.com/cgi-bin/cvsweb.cgi/cluster/gfs-kernel/src/gfs/log.h.diff?cvsroot=cluster&only_with_tag=RHEL4&r1=1.2&r2=1.2.2.1 http://sources.redhat.com/cgi-bin/cvsweb.cgi/cluster/gfs-kernel/src/gfs/ops_fstype.c.diff?cvsroot=cluster&only_with_tag=RHEL4&r1=1.13&r2=1.13.2.1
