For example, why does this not work?
It does for the write case for sure,
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.
