Subject: block: make blk_try_req_merge() static
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=e96c0d8336fdc5f1a6cae798bfa9c6e730001ad4;p=openwrt%2Fstaging%2Fblogic.git

block: make blk_try_req_merge() static

blk_try_req_merge() is only used in block/blk-merge.c, so make it
static.

This addresses a gcc warning when -Wmissing-prototypes is enabled.
