the same as fcntl() except that it supports the new 64-bit file locking commands (LINUX_F_GETLK64 etc) that use the `flock64' structure. We had been interpreting all flock structures passed to fcntl64() as `struct flock64' instead of only the ones from F_*64 commands. The glibc in linux_base-7 uses fcntl64() by default, but the bug was often non-fatal since the misinterpretation typically only causes junk to appear in the `l_len' field and most junk values are accepted as valid range lengths. The result is occasional EINVAL errors from F_SETLK and a few bytes after the supplied `struct flock' getting clobbered during F_GETLK.
