[S390] cio: deregister ccw device when pgid disband failed

2007-05-31T15:38:14+00:00

Deregister ccw device when device failure is detected during offline-
processing (e.g. when no last-path-gone indication was presented by
the hardware) to prevent the device from entering a non-recoverable
not-operational state.

[S390] cio: Use device_schedule_callback() for removing disconnected devices.

2007-05-31T15:38:12+00:00

We can't deregister disconnected and orphaned devices directly from
the online attribute's store method, but must take a detour.

[SCSI] zfcp: IO stall after deleting and path checker changes after reenabling zfcp devices

2007-05-16T14:01:38+00:00

IO stall after deleting and path checker changes after reenabling zfcp device

Setting one zfcp device offline using chccwdev in a multipath
environment and waiting will lead to IO stall on all paths.
After setting the zfcp device back online using chccwdev,
the devices with io stall will have a different path checker.
Devices corresponding to the deleted units are never freed.
This has the effect that 'slave_destroy' is never called and zfcp
still thinks that this unit is registered
(ZFCP_STATUS_UNIT_REGISTERED is still set). Hence the erp
routine is not called correctly and the unit is not enabled properly.

Do not delete rport and the sdev. Just set the host to block on
'offline'. Setting host online again will then remove the blocked status
and everything is fine again.

2007-05-16T14:01:38+00:00

avoid clutter in erp_dbf

cleanup zfcp_fsf_req_dismiss functions:
- avoid clutter in erp_dbf (reqs_active is always 0)
- fold called three-line function into calling function
- add meaningful comment
- coding style

[S390] Kconfig: use common Kconfig files for s390.

Disband drivers/s390/Kconfig, use the common Kconfig files. The s390
specific config options from drivers/s390/Kconfig are moved to the
respective common Kconfig files.
