This patch adds lots of weird and inexplicable single- and double-newlines in inappropriate places. However it frequently forgets to add newlines between end-of-locals and start-of-code, which is usual practice. +struct list_blocks_struct { + ext4_lblk_t first_block, last_block; + ext4_fsblk_t first_pblock, last_pblock; +}; This structure would benefit from some code comments.
