Apparently 4.4 took this breakage as an opportunity to improve the layout of `struct flock'. For some reason, there are no compatibility syscalls for fcntl() or flock() like there are for lseek(), mmap(), and other syscalls affected by the off_t change. It is too late to fix this now, because splitting the syscalls would break all 4.4 binaries that use them. Bruce
