btrfs: introduce helpers for subpage ordered status
This patch introduces the following functions to handle btrfs subpage
ordered (Private2) status:
- btrfs_subpage_set_ordered()
- btrfs_subpage_clear_ordered()
- btrfs_subpage_test_ordered()
These helpers can only be called when the range is ensured to be
inside the page.
- btrfs_page_set_ordered()
- btrfs_page_clear_ordered()
- btrfs_page_test_ordered()
These helpers can handle both regular sector size and subpage without
problem.
These functions are here to coordinate btrfs_invalidatepage() with
btrfs_writepage_endio_finish_ordered(), to make sure only one of those
functions can finish the ordered extent.
