The following patches were made over Martin's 5.12 scsi-fixes branch
which has this fix: 73603e995a37 ("scsi: iscsi: Fix iSCSI cls conn state")
that has conflicts with a patch in this set.
The patches fix TMF bugs in the qedi driver, libiscsi EH issues that are
common to all offload drivers like qedi and some fixes for cases where
userspace is not doing an unbind target nl cmd and we are doing TMFs
during session termination.
V3:
- Fix u16 initialization and test.
- Fix bool return value use.
- Added patches for cases where EH is running then userspace terminates
the connection without removing the target first.
- Made patch that stops IO during ep_disconnect more driver friendly
by handling if the ep is bound or not.
V2:
- Dropped patch that reverted the in-kernel conn failure handling. I
posted a full patchset to fix that separately.
- Modfied the tmf vs cmd queueing patch. The RFC patch only supported
qedi and offload drivers. iscsi_tcp/cxgbgi do not need it.
- Added patch for another issue found where cmds can still be queued to the
driver while it does ep_disconnect.
