[PATCH] Hold BKL for shorter period in generic_shutdown_super().
Testing revealed long pauses of the entire system while autofs initiated
umounts as a result of timing out the mounts.
It was noticed that during a umount, the BKL is held while scanning the
inode_list and removing and inodes that are candidates. This patch moves
locking until after the first pass had gone through the inode_list.
Testing revelead that on an ia64 machine with a filesystem that had 8.4
Million inodes, there were no observable pauses during the umount. This
was down from over 4 seconds without this patch.
