Bob Peterson d22f69a08d gfs2: Fix use-after-free in gfs2_logd after withdraw ... When the gfs2_logd daemon withdrew, the withdraw sequence called into make_fs_ro() to make the file system read-only. That caused the journal descriptors to be freed. However, those journal descriptors were used by gfs2_logd's call to gfs2_ail_flush_reqd(). This caused a use-after free and NULL pointer dereference. This patch changes function gfs2_logd() so that it stops all logd work until the thread is told to stop. Once a withdraw is done, it only does an interruptible sleep.
