Changes since v1: * Rename fex_end() and pa_end() to extent_logical_end() and pa_logical_end() to make the code more readable. * Refactor the logic for adjusting the best extent in ext4_mb_new_inode_pa() to simplify the code and remove redundant parameter for helper function. * Merged patch 4 to patch 1 as mainline commit 9d3de7ee192a fixed the issue.
