Subject: [PATCH v3 net-next] be2net: disable bh with spin_lock in be_process_mcc
Date: Tue, 6 Aug 2019 12:51:11 +0200 [thread overview]
Message-ID: <20190806105111.27058-1-dkirjanov@suse.com> (raw)
be_process_mcc() is invoked in 3 different places and
always with BHs disabled except the be_poll function
but since it's invoked from softirq with BHs
disabled it won't hurt.
v1->v2: added explanation to the patch
v2->v3: add a missing call from be_cmds.c
Signed-off-by: Denis Kirjanov <kda@linux-powerpc.org>
