1153 Here is a matrix of mmap possibilities:
1154 mmap private not fixed
1155 mmap private fixed at somewhere currently unmapped
1156 mmap private fixed at somewhere already mapped
1157 mmap shared not fixed
1158 mmap shared fixed at somewhere currently unmapped
1159 mmap shared fixed at somewhere already mapped
1160 For private mappings, we should verify that changes cannot be read()
1161 back from the file, nor mmap's back from the file at a different
1162 address. (There have been systems where private was not correctly
1163 implemented like the infamous i386 svr4.0, and systems where the
1164 VM page cache was not coherent with the filesystem buffer cache
1165 like early versions of FreeBSD and possibly contemporary NetBSD.)
1166 For shared mappings, we should conversely verify that changes get
1167 propogated back to all the places they're supposed to be.
1169 Grep wants private fixed already mapped.
1170 The main things grep needs to know about mmap are:
1171 * does it exist and is it safe to write into the mmap'd area
1172 * how to use it (BSD variants) */
