Subject: net: make symbol 'flush_works' static
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ce1e2a776ffcd5ce1570bf8f077ea0c26c1d8a8d;p=linux.git

net: make symbol 'flush_works' static

The sparse tool complains as follows:

net/core/dev.c:5594:1: warning:
 symbol '__pcpu_scope_flush_works' was not declared. Should it be static?

'flush_works' is not used outside of dev.c, so marks
it static.

Fixes: 41852497a9205 ("net: batch calls to flush_all_backlogs()")
