[PATCH 0/4] btrfs: bs > ps support preparation

[Qu Wenruo <wqu@suse.com>]

Some extra small and safe bs > ps support preparation, mostly focusing
on the bio vec iteration code and cached order/bit members.

This time the difference is, I can enable some early local bs > ps
tests, so basic file read/write and csum verification are all done
properly.

The tricky part is still inside the compression, and maybe some other
functionalities.

Qu Wenruo (4):
  btrfs: support all block sizes which is no larger than page size
  btrfs: cache max and min order inside btrfs_fs_info
  btrfs: replace single page bio_iter_iovec() usage
  btrfs: replace bio_for_each_segment usage
