[svn-r5390] Purpose:
Code cleanup
Description:
The parallel I/O file driver is optimized to only write metadata with one
process (and broadcast the results to the other processes). This is
currently enabled by a separate call to H5FD_mpio_tas_allsame() before
each metadata write to the file. This can easily lead to problems where
the prelude function call is omitted before the actual write code or, in
a threaded environment, lead to race condititions where the value set is
reset before being used.
Solution:
Since we only want to write metadata from one process, key off of the 'type'
parameter (which has information about whether the data being written it
metadata or raw data) to H5FD_mpio_write() as the method for determining
whether to only write from one process or not.
Platforms tested:
IRIX64 6.5 (modi4)
