sys/kern : vfs_subr.c
Log message:
When looping over mount points, the FOREACH SAVE macro is not save.
The loop variable mp is protected by vfs_busy() so that it cannot
be unmounted. But the next mount point nmp could be unmounted while
VFS_SYNC() sleeps. As the loop in vfs_stall() does not destroy the
mount point, TAILQ_FOREACH_REVERSE without _SAVE is the correct
macro to use.
