[PVFS2-CVS] commit by neill in pvfs2/src/io/trove/trove-dbpf: dbpf-dspace.c

[CVS commit program]

Update of /projects/cvsroot/pvfs2/src/io/trove/trove-dbpf
In directory parlweb:/tmp/cvs-serv14903/src/io/trove/trove-dbpf

Modified Files:
	dbpf-dspace.c 
Log Message:
- fixed type of readahead_size in upcall for mmap-ra-cache that caused
  the mmap-ra-cache to not work properly on PowerPC
- added some debugging to trove's iterate handles method that shows up
  on PowerPC at startup time (not yet sure why)
- do not look in the mmap-ra-cache for data on reads unless we're sure
  we're doing an mmap or execution that fits the bill for using the
  mmap-ra-cache (as opposed to always)
- removed kernel module pvfs2_link call, as it was never used
- misc cleanups
