Petersen" <martin.petersen@...cle.com> Subject: [PATCH 16/27] block: use bdev_alignment_offset in part_alignment_offset_show Replace the open coded offset calculation with the proper helper. This is an ABI change in that the -1 for a misaligned partition is properly propagated, which can be considered a bug fix and matches what is done on the whole device.
