Some of the reflink tests try to require a specific filesystem block size so that they can test file block manipulation functions. That's straightforward for most filesystems but ocfs2 throws in the additional twist that data fork block mappings are stored in units of clusters, not blocks, which causes these reflink tests to fail. Therefore, introduce a new helper that retrieves the file minimum block size and adapt the reflink tests to use that instead. Signed-off-by: Darrick J.

# See what happens if we DIO CoW blocks 2-4 of a page's worth of blocks when
|
|
# the second block is a unwritten block.
|
|
#
|
|
# This test is dependent on the system page size, so we cannot use md5 in
|
|
# the golden output; we can only compare to a check file.
