      [SCSI] lpfc 8.3.18: Adapter Shutdown and Unregistration cleanup · 5af5eee7
      由 James Smart 提交于 
      Adapter Shutdown and Unregistration cleanup

- Correct the logic around hba shutdown. Prior to final reset, the
  driver must wait for all XRIs to return from the adapter. Added logic
  to poll, progressively slowing the poll rate as delay gets longer.
- Correct behavior around the rsvd1 field in UNREG_RPI_ALL mailbox
  completion and final rpi cleanup.
- Updated logic to move pending VPI registrations to their completion
  in cases where a CVL may be received while registration in progress.
- Added unreg all rpi mailbox command before unreg vpi.

      [SCSI] lpfc 8.3.18: Add logic to detect last devloss timeout · a93ff37a
      由 James Smart 提交于 
      Added driver logic to detect the last devloss timeout of remote nodes which
was still in use of FCF. At that point, the driver should set the last
in-use remote node devloss timeout flag if it was not already set and should
perform proper action on the in-use FCF and recover of FCF from firmware,
depending on the state the driver's FIP engine is in.

Find eligible FCF through FCF table rescan or the next new FCF event when
FCF table rescan turned out empty eligible FCF, and the successful flogi
into an FCF shall clear the HBA_DEVLOSS_TMO flag, indicating the successful
recovery from devloss timeout.

      [SCSI] lpfc 8.3.18: FC/FCoE Discovery fixes · 5ac6b303
      由 James Smart 提交于 
      FC/FCoE Discovery fixes:

- Call the lpfc_drain_txq only for SLI4 hba
- In lpfc_cmpl_els_fdisc, fix code path that does not free IOCB.
- Treated firmware matching FCF property with different index as error
- Propagate error returns from lpfc_issue_els_flogi()
- Refactored lpfc_unregister_unused_fcf() to create a post
  lpfc_dev_loss_tmo handler call for SLI-4 devices. Allows checking of
  fcf after last ndlp released so that fcf can be released if no longer
  in use.
- Replaced individual FCF_XXXX_DISC flag clearing in lieu of aggregate
  FCF_DISCOVERY flag upon succesful completion of flogi.
- Correct setting of altBbCredit value in sparams to correct issue with
  logins with remote loop-based devices.

      [SCSI] lpfc 8.3.16: FCoE Discovery and Failover Fixes · 38b92ef8
      由 James Smart 提交于 
      - Add support for re-reg'ing changed VPI w/o unregister VPI
- Copy WWN and state from old nodelist when target DID change.
- Clean up old nodelist rport and put the nodelist when target DID change.
- Clear the VFI_REGISTERED flag when UNREG_VFI completes.
- Made both checks of port_state against LPFC_FLOGI and LPFC_FDISC
  non-inclusive for ignoring CVL events.
- Added logic to stop retrying of the ongoing PLOGI and FDISC if
  transitioned back to the FCF rediscovery state in reaction to CVL.
- Removed the dependency of scanning of all the available FCF table
  entries for bulding round-robin bitmap.
- Use the lpfc_sli4_fcf_rr_read_fcf_rec() in responding to
  individual New FCF found event.

      include cleanup: Update gfp.h and slab.h includes to prepare for breaking... · 5a0e3ad6
      由 Tejun Heo 提交于 
      include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h

percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files.  percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.

percpu.h -> slab.h dependency is about to be removed.  Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability.  As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.

  http://userweb.kernel.org/~tj/misc/slabh-sweep.py

The script does the followings.

* Scan files for gfp and slab usages and update includes such that
  only the necessary includes are there.  ie. if only gfp is used,
  gfp.h, if slab is used, slab.h.

* When the script inserts a new include, it looks at the include
  blocks and try to put the new include such that its order conforms
  to its surrounding.  It's put in the include block which contains
  core kernel includes, in the same order that the rest are ordered -
  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
  doesn't seem to be any matching order.

* If the script can't find a place to put a new include (mostly
  because the file doesn't have fitting include block), it prints out
  an error message indicating which .h file needs to be added to the
  file.

The conversion was done in the following steps.

1. The initial automatic conversion of all .c files updated slightly
   over 4000 files, deleting around 700 includes and adding ~480 gfp.h
   and ~3000 slab.h inclusions.  The script emitted errors for ~400
   files.

2. Each error was manually checked.  Some didn't need the inclusion,
   some needed manual addition while adding it to implementation .h or
   embedding .c file was more appropriate for others.  This step added
   inclusions to around 150 files.

3. The script was run again and the output was compared to the edits
   from #2 to make sure no file was left behind.

4. Several build tests were done and a couple of problems were fixed.
   e.g. lib/decompress_*.c used malloc/free() wrappers around slab
   APIs requiring slab.h to be added manually.

5. The script was run on all .h files but without automatically
   editing them as sprinkling gfp.h and slab.h inclusions around .h
   files could easily lead to inclusion dependency hell.  Most gfp.h
   inclusion directives were ignored as stuff from gfp.h was usually
   wildly available and often used in preprocessor macros.  Each
   slab.h inclusion directive was examined and added manually as
   necessary.

6. percpu.h was updated not to include slab.h.

7. Build test were done on the following configurations and failures
   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
   distributed build env didn't work with gcov compiles) and a few
   more options had to be turned off depending on archs to make things
   build (like ipr on powerpc/64 which failed due to missing writeq).

   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
   * powerpc and powerpc64 SMP allmodconfig
   * sparc and sparc64 SMP allmodconfig
   * ia64 SMP allmodconfig
   * s390 SMP allmodconfig
   * alpha SMP allmodconfig
   * um on x86_64 SMP allmodconfig

8. percpu.h modifications were reverted so that it could be applied as
   a separate patch and serve as bisection point.

Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.
