Subject: [Intel-wired-lan] [PATCH net-next 04/15] iavf: wrap driver state change in crit_section lock
Date: Fri,  4 Jun 2021 09:53:24 -0700	[thread overview]
Message-ID: <20210604165335.33329-4-anthony.l.nguyen@intel.com> (raw)
In-Reply-To: <20210604165335.33329-1-anthony.l.nguyen@intel.com>

From: Nicholas Nunley <nicholas.d.nunley@intel.com>

The changes to driver state in iavf_disable_vf() should be made inside
the crit_section lock, not outside of it, since the complete configuration
flow needs to be seen as one atomic operation.
