[PATCH 4/9] v4 Add mutex for add/remove of memory blocks
Add a new mutex for use in adding and removing of memory blocks. This is needed to avoid any race conditions in which the same memory block could be added and removed at the same time.

[PATCH 0/9] v4 De-couple sysfs memory directories from memory sections
This set of patches de-couples the idea that there is a single directory in sysfs for each memory section. The intent of the patches is to reduce the number of sysfs directories created to resolve a boot-time performance issue. On very large systems boot time are getting very long (as seen on powerpc hardware) d... 3 Aug 2010 10:20

[2.6.36, patch] unprotected access to task credentials in waitid()
Calling waitid [1] on a stopped process results in access to the task's credentials without the RCU read lock, which may change in the meantime, eliciting a warning [2]. This is fixed by: Ensure the task's credentials don't change before calling wait_noreap_copyout via acquisition of the RCU read lock. Sign... 3 Aug 2010 10:20

[PATCH 2/9] v4 Add new phys_index properties
Update the 'phys_index' properties of a memory block to include a 'start_phys_index' which is the same as the current 'phys_index' property. The property still appears as 'phys_index' in sysfs but the memory_block struct name is updated to indicate the start and end values. This also adds an 'end_phys_index' proper... 3 Aug 2010 10:20

[PATCH 3/9] v4 Add section count to memory_block
Add a section count property to the memory_block struct to track the number of memory sections that have been added/removed from a memory block. This allows us to know when the last memory section of a memory block has been removed so we can remove the memory block. Signed-off-by: Nathan Fontenot <nfont(a)austin.ib... 3 Aug 2010 10:20
