Revision 8648, 9.8 KB (checked in by shuangy, 3 years ago)

1. add >InitNumDirdataHandles?< field to fs_config and default value set to 2. 2. add command line options >-n, --init-num-dirdata< to pvfs2-mkdir to set initial number of dirdata handles for a directory. (not yet applied to kernel module.)
