Subject: [PATCH] don't do exit_io_context() until we know we won't be doing any IO

[PATCH] don't do exit_io_context() until we know we won't be doing any IO

testcase:

mount /dev/sdb10 /mnt
touch /mnt/tmp/b
umount /mnt
mount /dev/sdb10 /mnt
rm /mnt/tmp/b </mnt/tmp/b
umount /mnt

and watch blkdev_ioc line in /proc/slabinfo.  Vanilla kernel leaks.
