2018-01-22	btrfs: ref-verify: Remove unused parameter from walk_up_tree() to kill warning	Geert Uytterhoeven	1	-4/+2
	With gcc-4.1.2: fs/btrfs/ref-verify.c: In function ‘btrfs_build_ref_tree’: fs/btrfs/ref-verify.c:1017: warning: ‘root’ is used uninitialized in this function The variable is indeed passed uninitialized, but it is never used by the callee. However, not all versions of gcc are smart enough to notice. Hence remove the unused parameter from walk_up_tree() to silence the compiler warning.

2017-10-30	Btrfs: add a extent ref verify tool	Josef Bacik	1	-0/+1031
	We were having corruption issues that were tied back to problems with the extent tree. In order to track them down I built this tool to try and find the culprit, which was pretty successful. If you compile with this tool on it will live verify every ref update that the fs makes and make sure it is consistent and valid. I've run this through with xfstests and haven't gotten any false positives.
