RH-Commit: [23/26] 96e2e7d2e6a160ce4d695060f902d21030b3b1d8 (kmwolf/centos-qemu-kvm)

|
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.
