I think it'd be better to use sizeof(uint64_t) or something.

Actually, it's completely unnecessary.  iscsi_uevent contains a uint64_t
element, and the GCC docs (in the 'Type attribute' section, documenting
aligned) say:

     Note that the alignment of any given `struct' or `union' type is
     required by the ISO C standard to be at least a perfect multiple of
     the lowest common multiple of the alignments of all of the members
     of the `struct' or `union' in question.  This means that you _can_

So best to just delete it.  It has no effect.

Please check other spots, too. e.g.:

quoted

+	struct iscsi_stats_custom custom[0]
+		__attribute__ ((aligned (sizeof(unsigned long))));

This one's probably useless too, but it's hard to tell since the patches
weren't sent inline thus making them difficult to cross-reference.
