[PATCH 4/8] v5 Add mutex for add/remove of memory blocks

[PATCH 0/8] v5 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... 9 Aug 2010 14:34
