Subject: Revert "Btrfs: fix some error codes in btrfs_qgroup_inherit()"
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f3a87f1b0c4086a408eda48e4c26e32ff80d3124;p=linux-beck.git

Revert "Btrfs: fix some error codes in btrfs_qgroup_inherit()"

This reverts commit 5986802c2fcc754040bb7ed95f30bb16c4a843b7.

Both paths are not error paths but regular cases where non-qgroup
subvols are involved.
