haiku/headers/private/kernel/disk_device_manager/ddm_userland_interface.h
Tyler Dauwalder a03a04e027 - Added/moved ddm string-length and buffer-size constants to DiskDeviceDefs.h
- Converted all uses of B_{FILE,OS}_NAME_LENGTH in ddm_userland_interface.cpp
  to appropriate ddm constants.
- Made module names B_PATH_NAME_LENGTH long.
