Comment= # 7 on bug 96835<= /a> from Roland Scheidegger 
On second look, I am actually wondering if that commit really =
is doing the
right thing. Shouldn't we try to set the alignment on the struct itself
instead? And regardless, if someone uses an ordinary malloc for it it's not
going to be aligned anyway (meaning if it's passed to drivers somewhere and=
 the
called functions are relying on this to be aligned they might be in for some
surprise).

(That said I have no idea if this is really related to this bug.)
