This is 4 bytes on many 32-bit platforms, which may be less than the > default alignment for "__be64" (cfr. some members of struct > ovs_key_ipv4_tunnel), so this may make those 64-bit members unaligned. Do any of those 32-bit architectures actually care about alignment of 64 bit values? On 32-bit x86, a long is 32 bits but the alignment requirement of __be64 is also 32 bit. -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
