Subject: [PATCH v2 08/19] scsi: libsas: Pass gfp_t flags to event notifiers
Date:   Tue, 12 Jan 2021 12:06:36 +0100
Message-Id: <20210112110647.627783-9-a.darwish@linutronix.de>
In-Reply-To: <20210112110647.627783-1-a.darwish@linutronix.de>
References: <20210112110647.627783-1-a.darwish@linutronix.de>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Use the new libsas event notifiers API, which requires callers to
explicitly pass the gfp_t memory allocation flags.

Context analysis:

  - sas_enable_revalidation(): process, acquires mutex
  - sas_resume_ha(): process, calls wait_event_timeout()
