[PATCH 0/9] fuse: readdir caching

[Miklos Szeredi]

Allow caching readdir in fuse.  Use the page cache for this, which solves
cache shrinking on memory pressure.

I think it might make sense to extract something like this into a set of
VFS helpers, so that other filesystems can also make use of this facility.

Thanks,
Miklos
