Subject: [PATCH AUTOSEL 5.1 054/375] scsi: qla2xxx: Fix hardirq-unsafe locking
Date: Wed, 22 May 2019 15:15:54 -0400 [thread overview]
Message-ID: <20190522192115.22666-54-sashal@kernel.org> (raw)
In-Reply-To: <20190522192115.22666-1-sashal@kernel.org>
From: Bart Van Assche <bvanassche@acm.org>
[ Upstream commit 300ec7415c1fed5c73660f50c8e14a67e236dc0a ]
Since fc_remote_port_delete() must be called with interrupts enabled, do
not disable interrupts when calling that function. Remove the lockin calls
from around the put_sess() call. This is safe because the function that is
called when the final reference is dropped, qlt_unreg_sess(), grabs the
proper locks. This patch avoids that lockdep reports the following:
WARNING: HARDIRQ-safe -> HARDIRQ-unsafe lock order detected
kworker/2:1/62 [HC0[0]:SC0[0]:HE0:SE1] is trying to acquire:
