+ * 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.
