Looks good. Just one nitpick.

This requires a version change (0.1.1) before it can be picked up on main.
This mimics functionality from libfuse. When enabled, it will create a new file descriptor for each fuse thread by opening /dev/fuse again and using the FUSE_DEV_IOC_CLONE ioctl to associate the file handle with the original filesystem. Signed-off-by: Andrew Peace <[email protected]>

This mimics functionality from libfuse. When enabled, it will create a new file descriptor for each fuse thread by opening /dev/fuse again and using the FUSE_DEV_IOC_CLONE ioctl to associate the file handle with the original filesystem. The benefit of enabling this is that some of the processing queues in the kernel data structures are no longer shared, which theoretically reduces lock contention.
