Hi all,

Changes since 20110310:

The block tree lost its build failure but gained another for which I
applied a patch.

When CONFIG_BLOCK is not enabled:

mm/filemap.c:1257: error: storage size of 'plug' isn't known
mm/filemap.c:2450: error: storage size of 'plug' isn't known
mm/readahead.c:112: error: storage size of 'plug' isn't known
fs/aio.c:1625: error: storage size of 'plug' isn't known

Thanks Randy, I fixed it up.
