[PATCH 0 of 3] xen: sched_credit: fix tickling and add some tracing
Hello,
This small series deals with some weirdness in the mechanism with which the
credit scheduler choses what PCPU to tickle upon a VCPU wake-up. Details are
available in the changelog of the first patch.
The new approach has been extensively benchmarked and proved itself either
beneficial or harmless. That means it does not introduce any significant amount
of overhead and/or performances

RFC: [0/2] Remove netloop by lazy copying in netback
Hi Keir:
These two patches remove the need for netloop by performing the
copying in netback and only if it is necessary. The rationale
is that most packets will be processed without delay allowing
them to be freed without copying at all. So instead of copying
every packet destined to dom0 we''ll only copy those that linger
longer than a specified amount of time (currently 0.5s).
As it
