Description
In the Linux kernel, the following vulnerability has been resolved: gfs2: prevent NULL pointer dereference during unmount When flushing out outstanding glock work during an unmount, gfs2_log_flush() can be called when sdp->sd_jdesc has already been deallocated and sdp->sd_jdesc is NULL. Commit 35264909e9d1 (-gfs2: Fix NULL pointer dereference in gfs2_log_flush-) added a check for that to gfs2_log_flush() itself, but it missed the sdp->sd_jdesc dereference in gfs2_log_release(). Fix that.
