The virCgroupKill method kills all PIDs found in a cgroup
The virCgroupKillRecursively method does this recursively for child cgroups.
The virCgroupKillPainfully method does a recursive kill several times in a row until everything has really died
Do we really need three APIs, or can we just have:
virCgroupKill(..., VIR_CGROUP_KILL_RECURSIVE | VIR_CGROUP_KILL_PAINFUL)
I haven't reviewed the body of the patch, yet.
Agreed, I was surpized by this at first. Went though the patch my only remarks are rc = killedAny ? 1 : 0; is overkill since killedAny values seems only 0 or 1 anyway and the loop for virCgroupKillPainfully looks a bit arbitrary, sending 15 signals to all looks a lot, and the delay for the loop a bit short, if there is like a hundred processes in that group that could be a bit heavy, isn't it ?
