The first patch is a cleanup to remove the unused @fs_info parameter
from btrfs_csum_data().
The second patch uses btrfs_csum_data() directly to calculate super
block checksum and avoid use extent buffer helpers.
The final patch enhance btrfs_print_leaf() to be called with temporary
extent buffers in mkfs/convert, which have no eb->leaf populated.
Qu Wenruo (3):
btrfs-progs: remove the unused fs_info parameter for btrfs_csum_data()
btrfs: mkfs: do not use extent buffer to writeback super block
btrfs-progs: enhance btrfs_print_leaf() to handle NULL fs_info

This is a bit unfortunate, I need to fs_info parameter for checksumming functions for the authenticated hashes, I have a prototype and work on it in spare time. I'll probably apply this cleanup as I don't have ETA for the other patchset and some things are still not finalized.

In the function make_btrfs() we use a dummy extent buffer just to calculate the checksum for the super block. We do not need such workaround, and can manually call btrfs_csum_data() on @super, and pass @super directly to sbwrite(), completely avoid the need of a dummy extent buffer.

This makes debugging much harder that we can not use btrfs_print_leaf() to print the temporary tree blocks. There are only two things causing problems for btrfs_print_leaf() if eb->fs_info is NULL: - print_header_info() Which needs to grab the checksum type from eb->fs_info. This can be avoided by completely skipping checksum output if eb->fs_info is NULL. - btrfs_leaf_free_space() Which have two BUG_ON()s checking eb->fs_info, and finally calling BTRFS_LEAF_DATA_SIZE(). Which can be avoided by removing the two BUG_ON()s, and use __BTRFS_LEAF_DATA_SIZE(eb->len) to grab the same leaf data size. Thankfully all call sites inside mkfs and convert are setting eb->len to nodesize correctly. - __btrfs_print_leaf() Which calls BTRFS_LEAF_DATA_SIZE(eb->fs_info). Can be avoided by the same method above. With those changes, we can call btrfs_print_leaf() inside a debugger for temporary fses created by mkfs and convert.
