Before this patch, although btrfs_tree.h contains most of needed
structures for one to read on-disk btrfs data, it still has some missing
parts:
- Missing some structures and flags
Like btrfs_super_block, and BTRFS_INODE_* flags
- Not self-contained
It still needs to include <linux/btrfs.h>
- Uses old/deprecated comment style
This patchset will first move on-disk structure definition to
btrfs_tree.h first, making it self-contained.
Then reformat btrfs_tree.h to make it follow current comment style.
This patchset is mostly designed for incoming projects like U-boot to
share the kernel definitions more easily.
Changelog:
v2:
- Add the reason why we move the code
v3:
- Move more flags/enum shared with ioctl to btrfs_btree.h
This makes ioctl header to rely on btree_btree.h.
But this makes btrfs_tree.h completely self-consistent.
This problem is mostly exposed when syncing the header to btrfs-progs.
v4:
- Update btrfs_tree.h comment style
- Update btrfs_tree.h header define line
- Move enum btrfs_compression_type to btrfs_tree.h
