[libvirt] [PATCH v2 0/4] Optimize mass closing of FDs on child spwaning

Posted by Michal Privoznik 4 years, 9 months ago

v2 of:

https://www.redhat.com/archives/libvir-list/2019-July/msg00089.html

diff to v1:
- Added a test for stats parsing,
- Added big fat warning as requested by Eric that malloc() in between
  fork() and exec() is okay with glibc (I guess we don't care about
  other libc-s like musl or uclibc).

Michal Prívozník (4):
  virNetDevOpenvswitchInterfaceStats: Optimize for speed
  test: Introduce virnetdevopenvswitchtest
  vircommand: Separate mass FD closing into a function
  virCommand: use procfs to learn opened FDs
