Hi,
the screensaver?
The commit message should explain why track idle per seat.
Already when I read the cover letter, I was left wondering why do you
need to track idleness per seat? What actually is per-seat here?
Why would it matter which seat is getting user activity? It is all
still user activity and should prevent all idle-triggerings, right?
Then again, this patch is not implementing per-seat idle tracking, this
is implementing per-seat implicit idle-inhibit, which is triggered by a
key/botton/touch being down. Idle tracking sounds more like maintaining
a (per-seat) idle timer or a timestamp.
When I look at the weston code as a whole after this complete patch
series, I cannot find any use for per-seat idle_inhibit. It stays
global, just more complicated to compute.
Therefore I think this patch should be dropped.

These functions should not be removed and open-coded, but changed to
operate on a weston_seat.
