Subject: [PATCH v2 08/19] scsi: libsas: Pass gfp_t flags to event notifiers
Date: Tue, 12 Jan 2021 12:06:36 +0100 [thread overview]
Message-ID: <20210112110647.627783-9-a.darwish@linutronix.de> (raw)
In-Reply-To: <20210112110647.627783-1-a.darwish@linutronix.de>
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()
