Hello all,

The patches posted along with this cover letter are cleanups made
during the developement of subpagesize-blocksize patchset. I believe
that they can be integrated with the mainline kernel. Hence I have
posted them separately from the subpagesize-blocksize patchset.

I have testsed the patchset by running xfstests on ppc64 and
x86_64. On ppc64, some of the Btrfs specific tests and generic/255
fail because they assume 4K as the filesystem's block size. I have
fixed some of the test cases. I will fix the rest and mail them to the
fstests mailing list in the near future.

  Btrfs: __btrfs_buffered_write: Reserve/release extents aligned to
    block size
  Btrfs: Compute and look up csums based on sectorsized blocks
  Btrfs: Direct I/O read: Work on sectorsized blocks
  Btrfs: fallocate: Work with sectorsized blocks
  Btrfs: btrfs_page_mkwrite: Reserve space in sectorsized units
  Btrfs: Search for all ordered extents that could span across a page
  Btrfs: Use (eb->start, seq) as search key for tree modification log
  Btrfs: btrfs_submit_direct_hook: Handle map_length < bio vector length
  Btrfs: Limit inline extents to root->sectorsize
  Btrfs: Fix block size returned to user space
  Btrfs: Clean pte corresponding to page straddling i_size
