xfs: support in-memory buffer cache targets
Allow the buffer cache to target in-memory files by making it possible
to have a buftarg that maps pages from private shmem files. As the
prevous patch alludes, the in-memory buftarg contains its own cache,
points to a shmem file, and does not point to a block_device.
The next few patches will make it possible to construct an xfs_btree in
pageable memory by using this buftarg.
