8 * This used to be the part of array.c. See the rest of history and credits
9 * there. I took this into a separate file and switched the thing to generic
10 * proc_file_inode_operations, leaving in array.c only per-process stuff.
11 * Inumbers allocation made dynamic (via create_proc_entry()). AV, May 1999.
