I'd really like to fix this in some form, but not getting any response
[1][2][3].

Al, Linus, can you please comment?

I'm happy to take this through the overlayfs tree, just need an ACK for the
VFS API change.

Looks reasonable enough; I'm not too happy about yet another place LOOKUP_...
details get tangled into, though.  Do we want it to be more than just a
bool rcu?

I'd be fine with that change.   Calling with false/true is less
descriptive than calling with 0/LOOKUP_RCU but I guess we can leave
the actual calls to use the latter?

Thanks,
Miklos
