Looks pretty nice to me, thanks. I had a bunch of relatively minor review questions - mainly stuff which would benefit from some short comments. I had to do some mangling due to the intervening i_mmap_mutex->i_mmap_lock_read/write. I ended up choosing i_mmap_lock_read() throughout, which needs careful checking please. I also converted the changelogs. It still compiles! -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
