[PATCH 00/12] Fix Btrfs tests to work on non-4k block sized fs instances

This patchset fixes Btrfs tests to work on variable block size. This
is based off the RFC patch sent during March of this year
(https://www.marc.info/?l=linux-btrfs&m=142736088310300&w=2).

Currently, some of the tests are written with the assumption that 4k
is the block size of the filesystem instance. On architectures
(e.g. ppc64) with a larger page size (and hence larger block size),
these tests fail because the block bondaries assumed by the the tests
are no longer true and hence btrfs_ioctl_clone() (which requires a
block aligned file offset range) returns -EINVAL.

To fix the issue, This patchset adds three new filter functions:
1. _filter_xfs_io_blocks_modified
2. _filter_xfs_io_pages_modified
3. _filter_od

P.S: Since the changes made are trivial, I could have clubbed all the
patches into two patches. First patch introducing the new filtering
functions and the second patch containing the changes to made to the
tests. If this approach sounds right, I can post version V2 with the
two patches containing the relevant changes.

Filter xfs_io and od's output in units of FS block size and the CPU's
page size
