The current iter helper function deals with a hardware queue. Some
callers want to access all queues, like the internal blk-mq timeout
handling does. So add a helper for that.

Currently blk_mq_tag_busy_iter() loops all busy tags for a given
hardware queue. But sometimes we are looking for a specific request,
and when we find it, we don't have to keep looking over the rest of
them. Change the busy_iter_fn callback to return a bool, where a
true return will break out of
Instead of storing the IO tracker structure in a separate list
that we need to pop/push to on every submit and complete (and
lock), store it in the pdu associated with a request. This is
possible on scsi-mq only, and further cuts the spinlock associated
time for higher IOPS IO workloads. At 100K

Hi,
There's some low hanging fruit in the lsi mpt drivers for further
lock reduction, when running in scsi-mq mode. For each IO, they have
to lock/{get,put}/unlock a scsiio_tracker structure that is associated
with the IO. In scsi-mq mode, we can ask for some payload for each
command, so we don't
If a LLD has hardware commands in the request pdu, then we need some
helper hooks to help the driver initialize state at load time, and
potentially to tear down state at rmmod time. Add a host template
-init_command() and -exit_command() hook to help with that.

scsi_mq_scmd_to_pdu() returns the LLD pdu associated with a struct
scsi_cmnd.
scsi_mq_scmd_start() returns whether or not a given scsi command
has been started or not.

This is basically just a wrapper around blk_mq_queue_busy_iter(),
so that LLDs don't have to deal with or worry about blk-mq hardware
queues.

Hi everyone,
