2024-05-15T01:25:53+00:00

Pull SCSI updates from James Bottomley:
 "Updates to the usual drivers (ufs, lpfc, qla2xxx, mpi3mr, libsas).

  The major update (which causes a conflict with block, see below) is
  Christoph removing the queue limits and their associated block
  helpers.

  The remaining patches are assorted minor fixes and deprecated function
  updates plus a bit of constification"

scsi: libfc: Add some kernel-doc comments

2024-04-25T01:29:27+00:00

Complete the kernel-doc notation for enum fc_lport_state. This fixes 7
kernel-doc warnings.

 - In struct fc_rport_priv, change 'event_callback' to 'lld_event_callback'
   to match the struct member name.

 - In struct fc_fcp_pkt, add a description for 'timer_delay' to eliminate
   one kernel-doc warning.

 - Add return value notation for 3 functions. This fixes 3 kernel-doc
   warnings.

There are still 12 warnings for struct members not described in struct
fc_rport_priv and struct fc_lport, e.g:

libfc.h:218: warning: Function parameter or struct member 'event' not described in 'fc_rport_priv'
libfc.h:760: warning: Function parameter or struct member 'vlan' not described in 'fc_lport'

Warnings that are fixed in this patch:

libfc.h:75: warning: Enum value 'LPORT_ST_RNN_ID' not described in enum 'fc_lport_state'
libfc.h:75: warning: Enum value 'LPORT_ST_RSNN_NN' not described in enum 'fc_lport_state'

Merge patch series "convert SCSI to atomic queue limits, part 1 (v3)"

2024-04-12T10:35:55+00:00

Christoph Hellwig  says:

Hi all,

this series converts the SCSI midlayer and LLDDs to use atomic queue
limits API.  It is pretty straight forward, except for the mpt3mr
driver which does really weird and probably already broken things by
setting limits from unlocked device iteration callbacks.

I will probably defer the (more complicated) ULD changes to the next
merge window as they would heavily conflict with Damien's zone write
plugging series.  With that the series could go in through the SCSI
tree if Jens' ACKs the core block layer bits.

scsi: libata: Switch to using ->device_configure

2024-04-12T01:37:50+00:00

Switch to the ->device_configure method instead of ->slave_configure and
update the block limits on the passed in queue_limits instead of using the
per-limit accessors.

scsi: core: Add a device_configure method to the host template

2024-04-12T01:37:49+00:00

This is a version of ->slave_configure that also takes a queue_limits
structure that the caller applies, and thus allows drivers to reconfigure
the queue using the atomic queue limits API.

In the long run it should also replace ->slave_configure entirely as there
is no need to have two different methods here, and the slave name in
addition to being politically charged also has no basis in the SCSI
standards or the kernel code.

scsi: core: Add a no_highmem flag to struct Scsi_Host

2024-04-12T01:37:48+00:00

While we really should be killing the block layer bounce buffering ASAP, I
even more urgently need to stop the drivers to fiddle with the limits from
->slave_configure.  Add a no_highmem flag to the Scsi_Host to centralize
this setting and switch the remaining four drivers that use block layer
bounce buffering to it.

2024-04-12T01:37:48+00:00

ibmvfc only supports a single segment for BSG FC passthrough.  Instead of
having it set a queue limits after creating the BSG queues, add a field so
that the FC transport can set it before allocating the queue.
