*	block_device_operations->release() should return void	Al Viro	2013-05-07
\| \| \| \| \| \| \| \| \|	The value passed is 0 in all but "it can never happen" cases (and those only in a couple of drivers) and it would've been lost on the way out anyway, even if something tried to pass something meaningful. Just don't bother. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
*	s390/scm_blk: fix memleak in init function	Sebastian Ott	2013-04-26
\| \| \| \| \| \| \| \| \|	If the allocation of a single request fails the already allocated requests will not be freed. Reviewed-by: Peter Oberparleiter <oberpar@linux.vnet.ibm.com> Signed-off-by: Sebastian Ott <sebott@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
*	s390/scm_blk: fix error return code in scm_blk_init()	Wei Yongjun	2013-03-21
\| \| \| \| \| \| \| \| \|	Fix to return a negative error code from the error handling case instead of 0, as returned elsewhere in this function.

*	s390/scm_blk: suspend writes	Sebastian Ott	2013-03-07
\| \| \| \| \| \| \| \| \| \| \|	Stop writing to scm after certain error conditions such as a concurrent firmware upgrade. Resume to normal state once scm_blk_set_available is called (due to an scm availability notification).

*	s390/scm_blk: fix request number accounting	Sebastian Ott	2013-03-07
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	If a block device driver cannot fetch all requests from the blocklayer it's in his responsibility to call the request function at a later time. Normally this would be done after the next irq for the underlying device is handled. However in situations where we have no outstanding request we have to schedule the request function for a later time. This is determined using an internal counter of requests issued to the hardware. In some cases where we give a request back to the block layer unhandled the number of queued requests was not adjusted. Fix this class of failures by adjusting queued_requests in all functions used to give a request back to the block layer.
