 * #!-checking implemented by tytso.

 */

/*

 * Demand-loading implemented 01.12.91 - no need to read anything but

 * the header into memory. The inode of the executable is put into

 * "current->executable", and page faults do the actual loading. Clean.

 *

 * Once more I can proudly say that linux stood up to being changed: it

 * was less than 2 hours work to get demand-loading completely implemented.

 *

 * Demand loading changed July 1993 by Eric Youngdale.   Use mmap instead,

 * current->executable is only used by the procfs.  This allows a dispatch

 * table to check for several different types  of binary formats.  We keep

 * trying until we recognize the file or we run out of supported binary

 * formats.
