Subject[PATCH v2 0/3] vdpa_sim_blk: several fixes for the vDPA block simulator
Date
v2:
- Patch 2: restored previous behaviour, exiting the loop immediately if the
request is malformed [Jason]
- Added Jason's A-b In patch 1 and 3

v1: https://lore.kernel.org/virtualization/20220621160859.196646-1-sgarzare@redhat.com/

The first two patches essentially limit the possibility of the guest
doing a DoS to the host.

The third makes the simulator more correct (following what we do in
vdpa_sim_net) by calling vringh_complete_iotlb() in the error path as well.

Stefano Garzarella (3):
vdpa_sim_blk: use dev_dbg() to print errors
vdpa_sim_blk: limit the number of request handled per batch
vdpa_sim_blk: call vringh_complete_iotlb() also in the error path
