2013-09-11aoe: do not BUG if memory pressure prevented debugfs file creationEd Cashin1-1/+0
If the system has trouble allocating memory for the creation of the aoe debugfs directory or of a file inside it, the debugfs member of an aoedev can be NULL. Do not treat a NULL debugfs pointer as a BUG on aoedev shutdown, avoiding the user impact of an unecessary panic.

2013-09-11aoe: create and destroy debugfs directory for aoeEd Cashin1-1/+9
This series adds the debugging information that the coraid.com-distributed aoe driver exports via sysfs, but instead of sysfs, it uses debugfs. With these patches applied, even without AoE targets on the network, KEDR reports new possible memory leaks, but these are from callers outside the aoe driver that have used aoe_devnode to get the name of the character devices through the aoe_class->devnode callback, and I believe they're responsible for freeing that memory. This patch: Create and destroy the debugfs directory.

2013-09-11rtc: simplify devm_request_mem_region/devm_ioremapJulia Lawall9-107/+37
Convert the composition of devm_request_mem_region and devm_ioremap to a single call to devm_ioremap_resource. The associated call to platform_get_resource is also simplified and moved next to the new call to devm_ioremap_resource. This was done using a combination of the semantic patches devm_ioremap_resource.cocci and devm_request_and_ioremap.cocci, found in the scripts/coccinelle/api directory. In rtc-lpc32xx.c and rtc-mv.c, the local variable size is no longer needed. In rtc-ds1511.c the size field of the local structure is not useful any more, and is deleted.

2013-09-11cciss: set max scatter gather entries to 32 on P600Mike Miller1-0/+7
At one time we used to set the maximum number of scatter gather elements on all Smart Array controllers to 32. At some point in time the firmware began to write the "appropriate" value for each controller into the config table. The cciss driver would then read that and set h->maxsgentries. h->maxsgentries = readl(&(h->cfgtable->MaxSGElements); On the P600 that value is 544. Under some workloads a significant performance reduction may result. This patch forces the P600 to use only 32 scatter gather elements. Other controllers are not affected.
