Subject[RFT PATCH 0/4] fix / cleanup async scsi scanning
From
Date
Commit a7a20d10 "[SCSI] sd: limit the scope of the async probe domain"
introduces a boot regression by moving sd probe work off of the global
async queue. Using a local async domain hides the probe work from being
synchronized by wait_for_device_probe()->async_synchronize_full().

Fix this by teaching async_synchronize_full() to flush all async work
regardless of domain, and take the opportunity to convert scsi scanning
to async_schedule(). This enables wait_for_device_probe() to flush scsi
scanning work.

Lightly boot tested, Meelis does this fix your regression?

Thanks for your help.

Dan Williams (4):
async: introduce 'async_domain' type
async: make async_synchronize_full() flush all work regardless of domain
scsi: queue async scan work to an async_schedule domain
scsi: cleanup usages of scsi_complete_async_scans
