Detailed Description

Interface between the file system core and the file system formats.

A format implements struct pbl_fs_ops. The core resolves paths to a mount and hands the backend the path relative to the mount point, without the leading '/' ("" for the root of the mount). The core serializes nothing: backends are responsible for their own locking.
