Subject: writeback: make wb_start_writeback() static
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=9dfb176fae57a1dea68531fd25e867037e4d9bac;p=openwrt%2Fstaging%2Fblogic.git

writeback: make wb_start_writeback() static

We don't have any callers outside of fs-writeback.c anymore,
make it private.
