[PATCH v2 08/19] scsi: libsas: Pass gfp_t flags to event notifiers

Ahmed S. Darwish
2021-01-12T11:08:32Z

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()
