I mispoke, just for the record, the changes you mentioned actually don't
suffice for the test cases in question for test_sysfs, the deadlock
still occurs with those changes. At first I thought it did but I had failed
to remove my own fix first on fs/kernfs/dir.c. After removing that and
just trying the proposed changes I confirm it does not fix the deadlock.
