      [SCSI] Add target alloc/destroy callbacks to the host template · a283bd37
      James Bottomley authored
      
      
      This gives the HBA driver notice when a target is created and
      destroyed to allow it to manage its own target based allocations
      accordingly.
      
      This is a much reduced verson of the original patch sent in by
      James.Smart@Emulex.com

      [SCSI] TYPE_RBC cache fixes (sbp2.c affected) · 631e8a13
      Al Viro authored
      
      
      	a) TYPE_SDAD renamed to TYPE_RBC and taken to scsi.h
      	b) in sbp2.c remapping of TYPE_RPB to TYPE_DISK turned off
      	c) relevant places in midlayer and sd.c taught to accept TYPE_RBC
      	d) sd.c::sd_read_cache_type() looks into page 6 when dealing with
      TYPE_RBC - these guys have writeback cache flag there and are not guaranteed
      to have page 8 at all.
      	e) sd_read_cache_type() got an extra sanity check - it checks that
      it got the page it asked for before using its contents.  And screams if
      mismatch had happened.  Rationale: there are broken devices out there that
      are "helpful" enough to go for "I don't have a page you've asked for, here,
      have another one".  For example, PL3507 had been caught doing just that...
      	f) sbp2 sets sdev->use_10_for_rw and sdev->use_10_for_ms instead
      of bothering to remap READ6/WRITE6/MOD_SENSE, so most of the conversions
      in there are gone now.
      
      	Incidentally, I wonder if USB storage devices that have no
      mode page 8 are simply RBC ones.  I haven't touched that, but it might
      be interesting to check...
