Message

This patch series removes the use of buffer_heads from btrfs' super block read
and write paths.

The first patch removes buffer_heads from superblock reading.
The second from super_block writing and the subsequent patches remove the
buffer_heads from the integrity check code.

It's based on misc-next from Friday January 17, and doesn't show any
regressions in xfstests to the baseline.
