Subject: [PATCH v2 0/2] allow overlayfs to do RCU lookups

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.

Thanks,
Miklos

v2: just a minor fix for the CONFIG_FS_POSIX_ACL=n case.
