Jan Kara	828f12b965	dmhugedisk: Allow specifying of chunk size ... Ext4 will want to use dmhugedisk infrastructure for testing resize bugs. Ext4 fs images are rather sparse (especially with smaller block sizes) so the current chunk size of 512 sectors leads to large space consumption. Allow test to specify chunk size.

Darrick J. Wong	ffad9122b6	xfs: map multiple bmbt records to a single rmapbt record ... Make sure that we can handle multiple bmbt records mapping to a single rmapbt record. This can happen if you fallocate more than 2^21 contiguous blocks to a file. (Also add some helpers that can create huge devices with some dm-zero and dm-snapshot fakery.) Signed-off-by: Darrick J.
