Darrick J. Wong	1496a4f5e9	xfs/310: fix the size calculation for the huge device ... Fix the calculation of the dmhuge size. The previous calculation tried to calculate the size correctly, but got it wrong for 1k block sizes. Therefore, clean the whole mess up. Signed-off-by: Darrick J.

Darrick J. Wong	946b199460	xfs: use rmapbt-checking helper ... Don't open-code _notrun checks for the rmapbt, just use the helper. Signed-off-by: Darrick J.

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.
