The following patches made over Martin's 5.12 branches contain
fixes for a cmd lifetime bug, software iscsi can_queue setup,
and a couple of the lock cleanup patches Lee has already ackd.
V6:
- Remove task->sc check that is no longer needed because the
helper function we use does the check for us.
V5:
- Fix up KERN_ERR/INFO use when detecting invalid max_cmds values
from the user.
- Set iscsi_tcp can queue to max value it can support not including
mgmt cmds since the driver itself is not limited and that is a libiscsi
layer limit.
- Added the iscsi session class lock cleanup from the lock cleanup
patchset since it was reviewed already and this is now a patchset
for the next feature window.
V4:
- Add patch:
[PATCH 4/7] libiscsi: fix iscsi host workq destruction
to fix an issue where the user might only call iscsi_host_alloc then
iscsi_host_free and that was leaving the iscsi workqueue running.
- Add check for if a driver were to set can_queue to ISCSI_MGMT_CMDS_MAX
or less.
V3:
- Add some patches for issues found while testing.
- session queue depth was stuck at 128
- cmd window could not be detected when session was relogged in.
- Patch "libiscsi: drop taskqueuelock" had a bug where we did not
disable bhs and during xmit thread suspension leaked the current task.
V2:
- Take back_lock when looping over running cmds in iscsi_eh_cmd_timed_out
in case those complete while we are accessing them.
