rust: cpumask: Mark CpumaskVar as transparent

Browse source

[ Upstream commit 23fca458f6 ]

Unsafe code in CpumaskVar's methods assumes that the type has the same
layout as `bindings::cpumask_var_t`. This is not guaranteed by
the default struct representation in Rust, but requires specifying the
`transparent` representation.
