5 * glibc commit:
6 * 06ab719d30b0 ("Fix Linux fcntl OFD locks for non-LFS architectures (BZ#20251)")
7 * changed behavior of arg parameter for OFD commands. It is no
8 * longer passing arg directly to syscall, but expects it to be
9 * 'struct flock'.
10 *
11 * On 64-bit or _FILE_OFFSET_BITS == 64 we can use fcntl() and
12 * struct flock64 with any glibc version. struct flock and flock64
13 * should be identical.
14 *
15 * On 32-bit, older glibc would pass arg directly, recent one treats
16 * it as 'struct flock' and converts it to 'struct flock64'.
17 * So, to support both version, on 32-bit we use fcntl64 syscall
18 * directly with struct flock64.
