From: Christoph Hellwig Date: Fri, 15 Apr 2022 04:52:47 +0000 (+0200) Subject: block: use bdev_alignment_offset in part_alignment_offset_show X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=64dcc7c2717395b7c83ffb10f040d3be795d03c1;p=linux.git 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.
