It is nothing to do with where the admin request is sent, so no any
difference wrt. this issue between with and without this patchset,
right?

I'm afraid not.

For example:
  A scsi host has 8 LUNs associated with it.
  Before this patch set,
  When we send out the admin command, the budget is _per_ LUN, 1/8 of the total tags.
  After this patch set,
  When we send out the admin command, the budget is equal to _one_ LUN, 1/8 of the total tags.

However, the 1/8 above is different.
  Before the patch set, every LUN's admin command has 1/8 budget to use which is per LUN.
  After this patch set, all the 8 LUNs admin command has to share the 1/8 budget.
