Update.
2002-08-29 Ulrich Drepper <drepper@redhat.com> * libio/fileops.c (_IO_new_file_fopen): Recognize new mode specifier 'm' to enable mmap I/O. * libio/libio.h (_IO_FILE): Rename _blksize field to _flags2. The former wasn't used (anymore?). (_IO_FLAGS2_MMAP): New define. * libio/genops.c (_IO_no_init): Initialize _flags2 field. * libio/iofopen.c (__fopen_maybe_mmap): Use mmap callbacks only if _IO_FLAGS2_MMAP bit is set. * libio/iofdopen.c (_IO_new_fdopen): Recognize 'm' mode specifier. Enable mmap-using mode only if 'm' was set.
