      [IPV4]: Replace __in_dev_get with __in_dev_get_rcu/rtnl · e5ed6399
      由 Herbert Xu 提交于 
      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.

      由 Frank Pavlic 提交于 
      [patch 4/4] s390: qeth driver fixes .

From: Frank Pavlic <pavlic@de.ibm.com>
	- Clear read channel first prior to using ccw_device_set_offline.
	- use QETH_DBF_TEXT instead of QETH_DBF_SPRINTF
	- invoke qeth_halt_channel and qeth_clear_channel for all channels,
	  even if halt/clear for one of the channel fails.
	- enable qeth_arp_query function for GuestLAN devices

      Jeff,
I'm sorry seems that they have not been sent out either ...
ok here they come ...

[patch 3/4] s390: TSO related fixes in qeth driver

From: Frank Pavlic <pavlic@de.ibm.com>
	TSO related fixes :
	  - changing value of large_send attribute while network traffic
	    is running caused program check and thus device recovery.
	  - Due to hardware restriction discard packet when it exceeds 60K
	    otherwise qeth will cause program checks and thus traffic stall
	    when trying to send such huge packets.

      由 Frank Pavlic 提交于 
      Jeff,
sorry if I have flooded your inbox, I had some problems with the
mail server here yesterday, but it seems to be fixed ...
Ok patch 3-4 have no dependencies on patch 2 since only qeth driver is
affected.Thus I have made a new patch 2 for ctc driver.
Thank you .

      [PATCH] s390: debug feature changes · 66a464db
      由 Michael Holzheu 提交于 
      This patch changes the memory allocation method for the s390 debug feature.
Trace buffers had been allocated using the get_free_pages() function before.
Therefore it was not possible to get big memory areas in a running system due
to memory fragmentation.  Now the trace buffers are subdivided into several
subbuffers with pagesize.  Therefore it is now possible to allocate more
memory for the trace buffers and more trace records can be written.

In addition to that, dynamic specification of the size of the trace buffers is
implemented.  It is now possible to change the size of a trace buffer using a
new debugfs file instance.  When writing a number into this file, the trace
buffer size is changed to 'number * pagesize'.

In the past all the traces could be obtained from userspace by accessing files
in the "proc" filesystem.  Now with debugfs we have a new filesystem which
should be used for debugging purposes.  This patch moves the debug feature
from procfs to debugfs.

Since the interface of debug_register() changed, all device drivers, which use
the debug feature had to be adjusted.
