Subject: dm-verity: switch to bio_advance_iter_single()
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=17c0e16069765b319debba264c978c9a5c106e08;p=thirdparty%2Fkernel%2Flinux.git

dm-verity: switch to bio_advance_iter_single()

dm-verity doesn't support data blocks that span pages, and it sets
dma_alignment accordingly.  As such, instead of using
bio_advance_iter(), it can use the more lightweight function
bio_advance_iter_single() to get the same result.
