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().

Driver core: change sysdev classes to use dynamic kobject names

2008-01-25T04:40:40Z

All kobjects require a dynamically allocated name now. We no longer need to keep track if the name is statically assigned, we can just unconditionally free() all kobject names on cleanup. Signed-off-by: Kay Sievers Signed-off-by: Greg Kroah-Hartman

memory hotplug: rearrange memory hotplug notifier

2007-10-22T15:13:17Z

Current memory notifier has some defects yet. (Fortunately, nothing uses it.) This patch is to fix and rearrange for them. - Add information of start_pfn, nr_pages, and node id if node status is changes from/to memoryless node for callback functions. Callbacks can't do anything without those information. - Add notification going-online status. It is necessary for creating per node structure before the node's pages are available. - Move GOING_OFFLINE status notification after page isolation. It is good place for return memory like cache for callback, because returned page is not used again. - Make CANCEL events for rollingback when error occurs. - Delete MEM_MAPPING_INVALID notification. It will be not used. - Fix compile error of (un)register_memory_notifier(). Signed-off-by: Yasunori Goto Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

sparsemem: record when a section has a valid mem_map

2007-10-16T16:42:51Z

We have flags to indicate whether a section actually has a valid mem_map associated with it. This is never set and we rely solely on the present bit to indicate a section is valid. By definition a section is not valid if it has no mem_map and there is a window during init where the present bit is set but there is no mem_map, during which pfn_valid() will return true incorrectly. Use the existing SECTION_HAS_MEM_MAP flag to indicate the presence of a valid mem_map. Switch valid_section{,_nr} and pfn_valid() to this bit. Add a new present_section{,_nr} and pfn_present() interfaces for those users who care to know that a section is going to be valid.

more uevent fallout (drivers/base/memory.c)

Driver core: change add_uevent_var to use a struct

2007-10-12T21:51:01Z

This changes the uevent buffer functions to use a struct instead of a long list of parameters. It does no longer require the caller to do the proper buffer termination and size accounting, which is currently wrong in some places. It fixes a known bug where parts of the uevent environment are overwritten because of wrong index calculations. Many thanks to Mathieu Desnoyers for finding bugs and improving the error handling.

[PATCH] driver/base/memory.c: handle errors properly

Do proper error-checking and propagation in drivers/base/memory.c, hence fix __must_check warnings. Cc: KAMEZAWA Hiroyuki Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
