Subject: rcu: Remove needless initialization
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=cfed0a85dad921c683e9c0d25b072bcc5745ede0;p=linux-beck.git

rcu: Remove needless initialization

For global variables, C defaults all fields to zero.  The initialization
of the rcu_state structure's ->n_force_qs and ->n_force_qs_ngp fields
is therefore redundant, so this commit removes these initializations.
