From: Lukas Bulwahn Date: Tue, 15 Mar 2022 08:55:49 +0000 (+0100) Subject: srcu: Drop needless initialization of sdp in srcu_gp_start() X-Git-Tag: v5.19-rc1~252^2~1^5 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=586e31d59c436cda65a2e8ac04ff954bed247023;p=thirdparty%2Fkernel%2Flinux.git srcu: Drop needless initialization of sdp in srcu_gp_start() Commit 9c7ef4c30f12 ("srcu: Make Tree SRCU able to operate without snp_node array") initializes the local variable sdp differently depending on the srcu's state in srcu_gp_start(). Either way, this initialization overwrites the value used when sdp is defined. This commit therefore drops this pointless definition-time initialization. Although there is no functional change, compiler code generation may be affected. Signed-off-by: Lukas Bulwahn Signed-off-by: Paul E.
