Cover letter [PATCH 0/2] More nritems range checking
Hi,
thank you for applying my last patch, but regarding my corrputed file system I found two other cases were btrfs crashes:
- btrfs_del_items() was overlooked by me
- deleting from an empty node
Find attached two patches to improve that.
Please check the second patch hunk 2, as I'm unsure if "mid == nritems" is valid.
(If someone can give me a hand on how to get my FS fixed again, I would appreciate that.)
