Subject: nilfs2-add-bmap-function-to-seek-a-valid-key-fix
I've got a report from Dan Carpenter that this range check causes a
warning:
fs/nilfs2/btree.c:1611 nilfs_btree_seek_key() warn: impossible condition '(start > (~0)) => (0-u64max > u64max)'
A range check was needed there in a wip patch, but we no longer need
it.
