Subject: libceph: only call kernel_sendpage() via helper
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e36b13cceb46136d849aeee06b4907ad3570ba78;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

libceph: only call kernel_sendpage() via helper

Make ceph_tcp_sendpage() be the only place kernel_sendpage() is
used, by using this helper in write_partial_msg_pages().
