[PATCH 0/5] Enhance tree block validation checker

[Qu Wenruo <quwenruo.btrfs@gmx.com>]

The patchset can be fetched from github:
https://github.com/adam900710/linux/tree/checker_enhance

It's based on David's misc-next branch, with following commit as base:
a5e50b4b444c ("btrfs: Add checker for EXTENT_CSUM")

According to David's suggestion, enhance the output format of tree block
validation checker.

And move them into one separate file: tree-checker.c.

Some example output using btrfsck fsck-test images looks like:

For unagliend file extent member:
---
BTRFS critical (device loop0): corrupt leaf root=1 tree_block=29360128 slot=7 ino=257 file_offset=0: invalid file extent disk_bytenr, have 755944791, should be aligned to 4096
BTRFS error (device loop0): open_ctree failed
---

For bad leaf holes:
---
BTRFS critical (device loop0): corrupt leaf root=1 block=29360128 slot=28: uncontinuous item end, have 9387 expect 15018
BTRFS error (device loop0): open_ctree failed
---
