X-Git-Tag: fixes-v4.0-rc1~118^2~11
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=26e49cfc7e988a76bf1e55cef0d9e438e5489180;p=pandora-kernel.git

block: pass iov_iter to the BLOCK_PC mapping functions

Make use of a new interface provided by iov_iter, backed by
scatter-gather list of iovec, instead of the old interface based on
sg_iovec. Also use iov_iter_advance() instead of manual iteration.

This commit should contain only literal replacements, without
functional changes.
