memory_probe: fix wrong sysfs file attribute

2008-10-20T15:52:32Z

This attribute just has a write operation. [akpm@linux-foundation.org: use S_IWUSR as suggested by Randy] Signed-off-by: Shaohua Li Cc: Randy Dunlap Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

more sysdev API change fallout - drivers/base/memory.c

2008-07-28T15:31:58Z

Noticed because of this warning: drivers/base/memory.c:279: warning: initialization from incompatible pointer type Signed-off-by: Stephen Rothwell Signed-off-by: Linus Torvalds

Use WARN() in drivers/base/

2008-07-26T19:00:07Z

Use WARN() instead of a printk+WARN_ON() pair; this way the message becomes part of the warning section for better reporting/collection. Signed-off-by: Arjan van de Ven Cc: Greg KH Cc: Kay Sievers Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

memory-hotplug: add sysfs removable attribute for hotplug memory remove

2008-07-24T17:47:21Z

Memory may be hot-removed on a per-memory-block basis, particularly on POWER where the SPARSEMEM section size often matches the memory-block size. A user-level agent must be able to identify which sections of memory are likely to be removable before attempting the potentially expensive operation. This patch adds a file called "removable" to the memory directory in sysfs to help such an agent. In this patch, a memory block is considered removable if; o It contains only MOVABLE pageblocks o It contains only pageblocks with free pages regardless of pageblock type On the other hand, a memory block starting with a PageReserved() page will never be considered removable. Without this patch, the user-agent is forced to choose a memory block to remove randomly. Sample output of the sysfs files: ./memory/memory0/removable: 0 ./memory/memory1/removable: 0 ./memory/memory2/removable: 0 ./memory/memory3/removable: 0 ./memory/memory4/removable: 0 ./memory/memory5/removable: 0 ./memory/memory6/removable: 0 ./memory/memory7/removable: 1 ./memory/memory8/removable: 0 ./memory/memory9/removable: 0 ./memory/memory10/removable: 0 ./memory/memory11/removable: 0 ./memory/memory12/removable: 0 ./memory/memory13/removable: 0 ./memory/memory14/removable: 0 ./memory/memory15/removable: 0 ./memory/memory16/removable: 0 ./memory/memory17/removable: 1 ./memory/memory18/removable: 1 ./memory/memory19/removable: 1 ./memory/memory20/removable: 1 ./memory/memory21/removable: 1 ./memory/memory22/removable: 1 Signed-off-by: Badari Pulavarty Signed-off-by: Mel Gorman Acked-by: KAMEZAWA Hiroyuki Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

sysdev: Pass the attribute to the low level sysdev show/store function

2008-07-22T04:55:02Z

This allow to dynamically generate attributes and share show/store functions between attributes. Right now most attributes are generated by special macros and lots of duplicated code. With the attribute passed it's instead possible to attach some data to the attribute and then use that in shared low level functions to do different things. I need this for the dynamically generated bank attributes in the x86 machine check code, but it'll allow some further cleanups. I converted all users in tree to the new show/store prototype. It's a single huge patch to avoid unbisectable sections. Runtime tested: x86-32, x86-64 Compiled only: ia64, powerpc Not compile tested/only grep converted: sh, arm, avr32 Signed-off-by: Andi Kleen Signed-off-by: Greg Kroah-Hartman

driver core: register_memory/unregister_memory clean ups and bugfix

2008-04-20T02:10:19Z

register_memory()/unregister_memory() never gets called with "root". unregister_memory() is accessing kobject_name of the object just freed up. Since no one uses the code, lets take the code out. And also, make register_memory() static. Another bug fix - before calling unregister_memory() remove_memory_block() gets a ref on kobject. unregister_memory() need to drop that ref before calling sysdev_unregister().
