Subject: libceph: drop pages parameter
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=28a89ddece39890c255a0c41baf622731a08c288;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

libceph: drop pages parameter

The value passed for "pages" in read_partial_message_pages() is
always the pages pointer from the incoming message, which can be
derived inside that function.  So just get rid of the parameter.
