The addition of 64k block capability in the rec_len_from_disk and rec_len_to_disk functions added a bit of math overhead which slows down file create workloads needlessly when the architecture cannot even support 64k blocks. This will cut the corner. Signed-off-by: Ryusuke Konishi --- Reading git-diff-tree failed
