Subject: ceph: define ceph_writepages_osd_request()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=94fe8420bf519acd641ecbd442a0a79c1a024212;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ceph: define ceph_writepages_osd_request()

Mostly for readability, define ceph_writepages_osd_request() and
use it to allocate the osd request for ceph_writepages_start().
