      "message": "ocfs2: Optimize inode allocation by remembering last group\n\nIn ocfs2, the inode block search looks for the \"emptiest\" inode\ngroup to allocate from. So if an inode alloc file has many equally\n(or almost equally) empty groups, new inodes will tend to get\nspread out amongst them, which in turn can put them all over the\ndisk. This is undesirable because directory operations on conceptually\n\"nearby\" inodes force a large number of seeks.\n\nSo we add ip_last_used_group in core directory inodes which records\nthe last used allocation group. Another field named ip_last_used_slot\nis also added in case inode stealing happens. When claiming new inode,\nwe passed in directory\u0027s inode so that the allocation can use this\ninformation.\nFor more details, please see\nhttp://oss.oracle.com/osswiki/OCFS2/DesignDocs/InodeAllocationStrategy.\n\nSigned-off-by: Tao Ma \u003ctao.ma@oracle.com\u003e\nSigned-off-by: Mark Fasheh \u003cmfasheh@suse.com\u003e\n"

      "message": "ocfs2: Make ocfs2_extent_tree the first-class representation of a tree.\n\nWe now have three different kinds of extent trees in ocfs2: inode data\n(dinode), extended attributes (xattr_tree), and extended attribute\nvalues (xattr_value).  There is a nice abstraction for them,\nocfs2_extent_tree, but it is hidden in alloc.c.  All the calling\nfunctions have to pick amongst a varied API and pass in type bits and\noften extraneous pointers.\n\nA better way is to make ocfs2_extent_tree a first-class object.\nEveryone converts their object to an ocfs2_extent_tree() via the\nocfs2_get_*_extent_tree() calls, then uses the ocfs2_extent_tree for all\ntree calls to alloc.c.\n\nThis simplifies a lot of callers, making for readability.  It also\nprovides an easy way to add additional extent tree types, as they only\nneed to be defined in alloc.c with a ocfs2_get_\u003cnew\u003e_extent_tree()\nfunction.\n\nSigned-off-by: Joel Becker \u003cjoel.becker@oracle.com\u003e\nSigned-off-by: Mark Fasheh \u003cmfasheh@suse.com\u003e\n"
