2005-06-25[PATCH] s390: debug feature changesMichael Holzheu
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.

2005-06-13[SCSI] zfcp: fix bug during adapter shutdownAndreas Herrmann
Fixes a race between zfcp_fsf_req_dismiss_all and zfcp_qdio_reqid_check. During adapter shutdown it occurred that a request was cleaned up twice. First during its normal completion. Second when dismiss_all was called. The fix is to serialize access to fsf request list between zfcp_fsf_req_dismiss_all and zfcp_qdio_reqid_check and delete a fsf request from the list if its completion is triggered. (Additionally a rwlock was replaced by a spinlock and fsf_req_cleanup was eliminated.)

From: Maxim Shchetynin <maxim@de.ibm.com> Fixes a bug in zfcp_send_els_handler. If D_ID assignments for ports are changing between initiation of one ELS request and its completion the wrong port might be accessed in the completion for that ELS request. Thus a pointer to the port has to be passed for ELS requests to identify the port structure if required.

The old behaviour of allowing 6 retries with .5 seconds delay between retries was insufficient and qdio queues were shut down too erarly.

2005-05-15[PATCH] s390: set online race in the lcs driverFrank Pavlic
[patch 3/10] s390: set online race in the lcs driver. From: Michael Holzheu <holzheu@de.ibm.com> There is a race between lcs_stopcard() and lcs_open_device() which can lead to the error 'lcs: Error in starting channel, rc=-16'. lcs_open_device() is invoked when 'ifconfig up' is called due to a hotplug event, which is caused by register_netdev(). In parallel lcs_stopcard() is executed. Both functions are sending lcs commands. The second invocation fails with -EBUSY (-16) as return value. Move invocation of register_netdev() after invocation of lcs_stopcard to avoid the race. Signed-off-by: Frank Pavlic <pavlic@de.ibm.com>
