FWIW, for writes we're already being quite generous, in that plain aligned writes up to word-size are assumed to be "atomic" with the default (conservative) config, i.e. marking such writes is optional. Although, that's a generous assumption that is not always guaranteed to hold (https://lore.kernel.org/lkml/20190821103200.kpufwtviqhpbuv2n@willie-the-truc...).
Remind me to start writing everything in assembler.
That and to mark all structure members 'volatile'.
