[PATCH] s390: ccw device reconnect oops.

2005-10-11T16:46:53+00:00

Search for a disconnect ccw_device on the ccw bus rather than on the css
bus (was a typo in patch I did for the klist conversion).  A cast to an
embedding ccw_device from an embedded device in a struct subchannel will
lead us to oopses.

[PATCH] gfp flags annotations - part 1

2005-10-08T22:00:57+00:00

 - added typedef unsigned int __nocast gfp_t;

 - replaced __nocast uses for gfp flags with gfp_t - it gives exactly
   the same warnings as far as sparse is concerned, doesn't change
   generated code (from gcc point of view we replaced unsigned int with
   typedef) and documents what's going on far better.

[PATCH] s390: qeth driver fixes

2005-10-04T02:05:38+00:00

From: Peter Tiedemann 
From: Frank Pavlic 
	minor qeth fixes:
	- free old skb in qeth_realloc_headroom after duplicating skb
	- disable IPV6 support for Hipersockets devices
	- call ccw_device_set_offline on every channel regardless
	  of the return value of the prior ccw_device_set_offline calls
	- allocate qdio structures in DMA-area
	- schedule recovery of appropriate card
	  when cable has been inserted again.
	- add missing initialization of card->lock
	- write sequence number in skb->cb for SNA protocol which
	  requires strictly serialized packets.

[IPV4]: Replace __in_dev_get with __in_dev_get_rcu/rtnl

2005-10-03T21:35:55+00:00

The following patch renames __in_dev_get() to __in_dev_get_rtnl() and
introduces __in_dev_get_rcu() to cover the second case.

1) RCU with refcnt should use in_dev_get().
2) RCU without refcnt should use __in_dev_get_rcu().
3) All others must hold RTNL and use __in_dev_get_rtnl().

There is one exception in net/ipv4/route.c which is in fact a pre-existing
race condition.  I've marked it as such so that we remember to fix it.

This patch is based on suggestions and prior work by Suzanne Wood and
Paul McKenney.

[PATCH] driver core: add helper device_is_registered()

2005-09-22T14:58:24+00:00

add the helper and use it instead of open coding the klist_node_attached() check
(which is a layering violation IMHO)

idea by Alan Stern.

[SCSI] zfcp: add additional fc_host attributes

2005-09-19T18:04:15+00:00

this patch adds some fc host attributes and removes its equivalents
from the zfcp_adapter structure and zfcp specific sysfs subtree.

Furthermore it removes superfluous calls to fc_remort_port_delete when
an adapter is set offline because rports will be removed by
fc_remove_host anyway.

[SCSI] zfcp: provide support for NPIV

2005-09-19T18:03:45+00:00

N_Port ID Virtualization (NPIV) allows a single FCP port to appear as
multiple, distinct ports providing separate port identification. NPIV
is supported by FC HBAs on System z9. zfcp was adapted to support this
new feature.

[SCSI] zfcp: enhancement of zfcp debug features

2005-09-19T18:03:00+00:00

Debug features (DBFs) els_dbf, cmd_dbf and abt_dbf were removed and
san_dbf, hba_dbf and scsi_dbf were introduced. The erp_dbf did not
change.
The new traces improve debugging of problems with zfcp, scsi-stack,
multipath and hardware in the SAN. san_dbf traces things like ELS and
CT commands, hba_dbf saves HBA specific information of requests, and
scsi_dbf saves FCP and SCSI specific information of requests. Common
to all new DBFs is that they provide a so called structured view. This
significantly improves readability of the traces.
