2005-09-05[PATCH] s390: deadlock in dasd_devmapHorst Hummel6-41/+24
Reintroduce a read-only copy of the devmap features in the device struct. This is necessary to solve a deadlock on the dasd_devmap_lock which is acquired by dasd_get_features called from the dasd tasklet. The current implementation of devmap doesn't allow to call any devmap function from interrupt or softirq context.

2005-09-05[PATCH] s390: machine check handler bugsMartin Schwidefsky1-1/+1
The new machine check handler still has a few bugs. 1) The system entry time has to be stored in the machine check handler, 2) the machine check return psw may not be stored at the usual place because it might overwrite the return psw of the interrupted context, 3) the return address for the call to s390_handle_mcck in the i/o interrupt handler is not correct, 4) the system call cleanup has to take the different save area of the machine check handler into account, 5) the machine check handler may not call UPDATE_VTIME before CREATE_STACK_FRAME, and 6) the io leave path needs a critical section cleanup to make sure that the TIF_MCCK_PENDING bit is really checked before switching back to user space.

Close a small window where a device may be not operational again after senseid finished and the "same device" check fails due to dev=0000 by checking for dnv after stsch() by then setting the device to not operational. (No need to check for dnv in ccw_device_handle_oper() again since we don't do stsch() into the subchannel's schib in the meantime and will get a crw anyway if the device becomes not oper again).

2005-07-27[PATCH] clean up inline static vs static inlineJesper Juhl2-23/+23
`gcc -W' likes to complain if the static keyword is not at the beginning of the declaration. This patch fixes all remaining occurrences of "inline static" up with "static inline" in the entire kernel tree (140 occurrences in 47 files). While making this change I came across a few lines with trailing whitespace that I also fixed up, I have also added or removed a blank line or two here and there, but there are no functional changes in the patch.

2005-07-27[PATCH] s390: fba dasd i/o errorsHorst Hummel1-1/+3
The FBA discipline does not use retries for failed requests. A request fails after the first unsuccessful start attempt. There are some rare conditions (e.g. CIO path recovery) in which the start of an i/o on a fba device can fail. A tiny amount of retries is therefore reasonable.

2005-07-08[NET]: Transform skb_queue_len() binary tests into skb_queue_empty()David S. Miller2-5/+5
This is part of the grand scheme to eliminate the qlen member of skb_queue_head, and subsequently remove the 'list' member of sk_buff. Most users of skb_queue_len() want to know if the queue is empty or not, and that's trivially done with skb_queue_empty() which doesn't use the skb_queue_head->qlen member and instead uses the queue list emptyness as the test.

2005-06-25[PATCH] s390: debug feature changesMichael Holzheu17-66/+68
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.

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.)
