Description of problem: btrfs check complains about a bunch of error like this one: bad extent [347045888, 347062272), type mismatch with chunk which are false positives. Version-Release number of selected component (if applicable): [dan@tauron backup]$ btrfs --version btrfs-progs v4.3.1 How reproducible: run btrfs check on a filesystem that triggers the false positive Actual results: btrfs reports false positives about mismatched chunks Expected results: btrfs doesn't report false positives Additional info: This is a bug recognized by upstream and fixed in version 4.4.1 [1]. The mismatch check was introduced to recognize some filesystems created with mkfs.btrfs v.4.1.1 [2], but it produced false positives on some correct filesystems. A simple fix for this bug is to update Fedora's package to btrfs-progs 4.4.1 or later. I compiled the same version from source and it's not reporting any errors on my filesystem.

Ok, easy enough to push 4.4.1 over, thanks. -Eric
