From: bmarzins@sourceware.org To: cluster-cvs@sources.redhat.com Subject: cluster/gfs-kernel/src/gfs glock.c Date: Thu, 24 Jan 2008 20:08:00 -0000 [thread overview] Message-ID: <20080124200844.18311.qmail@sourceware.org> (raw) CVSROOT: /cvs/cluster Module name: cluster Branch: RHEL51 Changes by: bmarzins@sourceware.org 2008-01-24 20:08:43 Modified files: gfs-kernel/src/gfs: glock.c Log message: Fix for bz #426291. gfs_glock_dq was traversing the gl_holders list without holding the gl_spin spinlock, this was causing a problem when the list item it was currently looking at got removed from the list. The solution is to not traverse the list, because it is unncessary. Unfortunately, there is also a bug in this section of code, where you can't guarantee that you will not cache a glock held with GL_NOCACHE. Fixing this issue requires significantly more work. Patches: http://sourceware.org/cgi-bin/cvsweb.cgi/cluster/gfs-kernel/src/gfs/glock.c.diff?cvsroot=cluster&only_with_tag=RHEL51&r1=1.29.2.5&r2=1.29.2.5.2.1
