The 'inuse' bitmap is local to this function. So we can use the

While at it, also remove some useless {}.
I like the {} and tend to add it in new code. There isn't a rule about
this one way or the other.

Hi Dan,
- checkpatch prefers the style without {}
- Usually, greg k-h and Joe Perches give feed-back that extra {} should
be removed.
- in https://www.kernel.org/doc/html/v5.13/process/coding-style.html,
after "Rationale: K&R":
"Do not unnecessarily use braces where a single statement will do."
My own preference is to have {}. It is the standard used on another
project I work on (i.e. httpd) and it helps when you add some code (it
avoids unexpected behavior if you forget to add some missing {})
My understanding is that on the HUGE code base of Linux, emphasis is put
on saving some lines of code, reducing the length of lines and avoiding
the need to read some extra char.
I'm also fine with it.
