I was just lamenting that decision. I think someone persuaded me that
the extra complexity wasn't worth it, and that we should just do it
unconditionally. 

One option would be to restore the FS_NO_LOOKUP_IN_READDIR flag, and
document that it means that your ->lookup is called _without_ i_mutex
held. That would actually be OK in all cases that need the flag, I
believe (since the whole point in those cases is that they have their
_own_ locking which is why we did it in the first place).
