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.
