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.
