Subject: [PATCH v3 08/19] scsi: libsas: Pass gfp_t flags to event notifiers
Date: Mon, 18 Jan 2021 11:09:44 +0100
Message-ID: <20210118100955.1761652-9-a.darwish@linutronix.de> (raw)
In-Reply-To: <20210118100955.1761652-1-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()
