I will test your patch later.
Git-bisect gave me this result thus far:
9026e521c0da0731eb31f9f9022dd00cc3cd8885 is bad 82f04ab47e1d94d78503591a7460b2cad9601ede is good
When I continue the bisection with 4345caba340f051e10847924fc078ae18ed6695c the system will start normally, but it then silently corrupts my xfs partitions. And on next (re)boot I get this (only fixable with xfs_repair):
