haiku/headers/private/kernel/disk_device_manager/KFileSystem.h
Axel Dörfler 47f39c93cb Merged the disk device manager module interface for file systems with the
VFS's interface, so that a file system only has to implement one interface.
As a side effect, the automatic file system detection may now work (not yet
tested, though).
