Any library providing common used structures and algorithms for FUSE

I am going to write a file system prototype by using FUSE. Are there any (additional) well implemented libraries bes开发者_开发技巧ides FUSE that can provide some common file system optimizing functions like dir cache, journaling, lookup table, atomic ops and etc. It should be better written in C.

By the way, I am going to implement it on OSX and Linux. That's one of the major concerns I will use FUSE but not a native file system, even the performance matters.

Thanks.

On Windows, the Dokan library has been around for a while. I've been meaning to play with it, but haven't had the chance. It is a file system driver that forwards all activity back to a user mode process, and a DLL that facilitates writing the user mode side. It is open source, and licensed in a mix of LGPL and MIT licenses.

There was an emulation (or perhaps a port) of FUSE for Windows once called WinFUSE, but my links to it are all dead now. It may be findable...

Edit: There is an extensive List of Filesystems at Wikipedia. It doesn't appear to list many options on Linux outside of FUSE. The others that appear at first glance to be similar, are often implemented on top of FUSE.

The exception seems to be LUFS (Linux Userland File System), but work on it appears to have been abandoned in 2003 in favor of FUSE.
