[Xen-devel] [PATCH 07/23] libxl: events: const-correct *_inuse, *_isregistered

[Ian Jackson <ian.jackson@xxxxxxxxxxxxx>]

The comments for libxl__ev_time_isregistered and the corresponding
watch function even say that these should be const.  Make it so.

Also fix libxl__ev_child_inuse and libxl__ev_spawn_inuse.
