[PATCH] fuse: support caching negative dentries
Add support for caching negative dentries.
Up till now, ->d_revalidate() always forced a new lookup on these. Now let
the lookup method return a zero node ID (not used for anything else) meaning a
negative entry, but with a positive cache timeout. The old way of signaling
negative entry (replying ENOENT) still works.
Userspace should check the ABI minor version to see whether sending a zero ID
is allowed by the kernel or not.
