Have any of you run xfstests without failures?
I'm finding it hard to believe, as some of these changes cause
problems all the time, and at least one of them deterministically
("btrfs: fix validation of XATTR_ITEM dir items"), as I've just noted
in the respective thread for that patch.
I haven't traced which change is causing a BUG_ON in the raid56 code,
due to lack of time, but running btrfs tests from 060 to 074 triggers
it very easily, for example:
