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-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=586e31d59c436cda65a2e8ac04ff954bed247023;p=linux.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.
