[svn-r7460] Purpose:
Update
Description:
Added extra parameter to the H5AC_protect() function that indicates
if the cache being asked for is going to be written to or just read
from. Those AC_protect calls that were H5AC_find calls are now
read-only. The rest are writes.
Platforms tested:
Linux (h5committest not needed due to size and small impact)
Misc. update:
