The following series of patches add support creating and checking filesystems with the FLEX_BG feature. This feature currently groups meta-data from a series of groups at the beginning of a flex group in order to improve performance during heavy meta-data operations. Changes from last time: - When making a filesystem with FLEX_BG also enable META_BG feature. - Allocate meta data within the META_BG group range. - Descriptor checking ensures bitmaps and inode tables are in the META group. Problems and TODOs: - Fsck has some failures using FLEX_BG and resize_inode features at the same time. Still investigating. - Need to define how unallocated inode tables will look like. - Need to create test case -JRS - To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
