Subject: rcu: Make nocb_nobypass_lim_per_jiffy static
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=9640dcab974fb7fba086d30fd9f0ec08b8876d12;p=linux.git

rcu: Make nocb_nobypass_lim_per_jiffy static

RCU triggerse the following sparse warning:

kernel/rcu/tree_plugin.h:1497:5: warning: symbol
'nocb_nobypass_lim_per_jiffy' was not declared. Should it be static?

This commit therefore makes this variable static.
