Btrfs: flush out and clean up any block device pages during mount
Btrfs puts the filesystem metadata into its own address space, and
somehow the block device address space isn't getting onto disk properly
before a mount. The end result is that a loop of mkfs and mounting the
filesystem will sometimes find stale or incorrect data.
This commit should fix it by sprinkling fdatawrites and invalidate_bdev
calls around. This is a short term measure to make sure it is fixed.
The block devices really should be flushed and cleaned up higher in the
stack.
