block/iscsi: handle failure on malloc of the allocationmap (2014-09-30
13:30:51 +0200)
----------------------------------------------------------------
This update brings dataplane to virtio-scsi (NOT
yet 100% thread-safe, though, which makes it really, really
experimental. It also brings asynchronous cancellation to
the SCSI subsystem and implements it in virtio-scsi. This
is a pretty important feature. Almost all the work here
was done by Fam Zheng.
I also included the virtio refcount fixes from Gonglei,
because they had a small conflict with virtio-scsi dataplane.
This pull request is using the new subkey 4E6B09D7.
