[libvirt] [PATCH 0/3] Optimize mass closing of FDs on child spwaning

[Michal Privoznik]

If the limit for max opened files is way bigger than the default (1024),
say 3 orders bigger then spawning a child through virCommand can be
expensive because we iterate over ALL FDs within the limit and close
them. There's no need to that since we can learn the list of opened FDs
from /proc/self/fd/.

Michal Prívozník (3):
  virNetDevOpenvswitchInterfaceStats: Optimize for speed
  vircommand: Separate mass FD closing into a function
  virCommand: use procfs to learn opened FDs
