2015-07-17flowtop, netsniff-ng: Move process name extraction to own functionTobias Klauser1-0/+15
flowtop and the netsniff-ng's netlink message dissector both need to get the process name for a pid from /proc/<pid>/exe, thus move that functionality to an own function. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>

KVM: shrink halt polling even more for invalid wakeups
commit 3491caf2755e ("KVM: halt_polling: provide a way to qualify wakeups during poll") added more aggressive shrinking of the polling interval if the wakeup did not match some criteria. This still allows to keep polling enabled if the polling time was smaller that the current max poll time (block_ns <= vcpu->halt_poll_ns). Performance measurement shows that even more aggressive shrinking (shrink polling on any invalid wakeup) reduces absolute and relative (to the workload) CPU usage even further.
