Subject: [PATCH 00/10] Fix scsi devices plug/unplug races w.r.t virtio-scsi iothread
Date: Fri, 25 Sep 2020 13:25:54 -0400 [thread overview]
Message-ID: <20200925172604.2142227-1-pbonzini@redhat.com> (raw)
This is my take on Maxim's patches. Mostly I am avoiding the problems with
"scsi/scsi_bus: switch search direction in scsi_device_find" by adding
a pre-realize callback for BusState that checks for the device address
being in use.
This makes it possible to avoid the tricky search for a preexisting device.
Maxim Levitsky (7):
scsi/scsi_bus: switch search direction in scsi_device_find
device_core: use drain_call_rcu in in hmp_device_del/qmp_device_add
device-core: use RCU for list of children of a bus
device-core: use atomic_set on .realized property
scsi/scsi_bus: Add scsi_device_get
virtio-scsi: use scsi_device_get
scsi/scsi_bus: fix races in REPORT LUNS
Paolo Bonzini (3):
qdev: add "check if address free" callback for buses
scsi: switch to bus->check_address
scsi/scsi-bus: scsi_device_find: don't return unrealized devices
