Steven Whitehouse 54335b1fca GFS2: Cache the most recently used resource group in the inode ... This means that after the initial allocation for any inode, the last used resource group is cached in the inode for future use. This drastically reduces the number of lookups of resource groups in the common case, and this the contention on that data structure. The allocation algorithm is the same as previously, except that we always check to see if the goal block is within the cached rgrp first before going to the rbtree to look one up.
