/*
 * glibc commit:
 *   06ab719d30b0 ("Fix Linux fcntl OFD locks for non-LFS architectures (BZ#20251)")
 * changed behavior of arg parameter for OFD commands. It is no
 * longer passing arg directly to syscall, but expects it to be
 * 'struct flock'.
 *
 * On 64-bit or _FILE_OFFSET_BITS == 64 we can use fcntl() and
 * struct flock64 with any glibc version. struct flock and flock64
 * should be identical.
 *
 * On 32-bit, older glibc would pass arg directly, recent one treats
 * it as 'struct flock' and converts it to 'struct flock64'.
 * So, to support both version, on 32-bit we use fcntl64 syscall
 * directly with struct flock64.
