Was this fixed by a kernel commit to the XFS tree?  If so, could you
add a _fixed_by_kernel_commit pointing at the fix?  And while you're
at it, could you add:


[ $FSTYP == "ext4" ] && \
	_fixed_by_kernel_commit 273108fa5015 \
	"ext4: handle read only external journal device"

to the test?  This will make it easier for people using LTS kernels to
know which commits they need to backport.

Many thanks!
