/* The posix_file_record_ref structure maintains necessary runtime metadata
* for the POSIX file record (darshan_posix_file structure, defined in
* darshan-posix-log-format.h) pointed to by 'file_rec'. This metadata
* assists with the instrumenting of specific statistics in the file record.
*
* RATIONALE: the POSIX module needs to track some stateful, volatile
* information about each open file (like the current file offset, most recent
* access time, etc.) to aid in instrumentation, but this information can't be
* stored in the darshan_posix_file struct because we don't want it to appear in
* the final darshan log file. We therefore associate a posix_file_record_ref
* struct with each darshan_posix_file struct in order to track this information
* (i.e., the mapping between posix_file_record_ref structs to darshan_posix_file
* structs is one-to-one).
*
* NOTE: we use the 'darshan_record_ref' interface (in darshan-common) to
* associate different types of handles with this posix_file_record_ref struct.
* This allows us to index this struct (and the underlying file record) by using
* either the corresponding Darshan record identifier (derived from the filename)
* or by a generated file descriptor, for instance. So, while there should only
* be a single Darshan record identifier that indexes a posix_file_record_ref,
* there could be multiple open file descriptors that index it.
