[PULL 26/33] scsi: remove outdated AioContext lock comment
Posted by Kevin Wolf 11 months, 1 week ago
From: Stefan Hajnoczi <stefanha@redhat.com>

The SCSI subsystem no longer uses the AioContext lock. Request
processing runs exclusively in the BlockBackend's AioContext since
"scsi: only access SCSIDevice->requests from one thread" and hence the
lock is unnecessary.
