Re: [Xen-devel] [PATCH] xen: sched: adjustments to some performance counters

More specifically:
1) rename vcpu_destroy to vcpu_remove
It seems this have had to be done as part of 7e6b926a
("cpupools: Make interface more consistent"), which
renamed the function but not the counter.
In fact, because of cpupools, vcpus are not only removed
from a scheduler when they are destroyed, but also when
domains move between pools.
Make the related statistics counter reflect that more
properly.
2) rename vcpu_init to vcpu_alloc
As it lives in *_alloc_vdata.
3) add vcpu_insert
matching vcpu_remove, and useful to quickly check
whether the number of insertions and removal matches,
or in general investigare their relationship.

This would be v2 of "xen: sched: rename vcpu_destroy perf counter to
vcpu_remove", but both the title and the content changed, so I'm treating it as
a fresh submission (and not applying the Rev-by Juergen gave to it).
You can have it again:
