Subject: [PATCHSET 3/6] fuse2fs: add some easy new features

Hi all,

As of 2025, libfuse is a lot more capable than it was in 2013.
Implement some new features such as readdirplus and directory seeking
for better directory performance, and reduce the amount of filesystem
flushing so that it only happens when userspace explicitly asks for it.

If you're going to start using this code, I strongly recommend pulling
from my git trees, which are linked below.

Comments and questions are, as always, welcome.
