In all prior versions, the file name was checked whether it contains
character ':'. The prefix name ending with ':' is considered by ROMIO as
the file system type name. The prefix name, if found, is then stripped, so
the file name can be used in the successive POSIX function calls. However,
the prefix was not checked against the file system type names recognized
by ROMIO. Starting from this release, the prefix is checked against the
known file system type names to ROMIO. If the prefix is not one of the
recognized types, then the prefix name is
not stripped. This change is for in case when the file name contains ':',
but it is not for specifying the file system type.
Currently (ROMIO in MPICH 4.0.1), the following file system types are defined:
