Hello List, Here is a proposal to enable ext4 allocate blocks across group boundary. Now ext4 allocates blocks within a single block group by locking a group. Flex_bg puts metadata blocks together, as a result,it enlarges contiguous blocks. So we can enable ext4 allocate blocks within a flex block group. Inode allocation takes group lock as block allocation, I am not sure if we should allocate inode within single group as before. If we do this, then the new group boundary will be flex block group boundary. I am not sure if it is worth doing. Any ideas? -- Best Wishes Yongqiang Yang -- 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
