Subject: cgroups and overcommit question
Date: Wed, 12 Jan 2011 18:40:37 +0300	[thread overview]
Message-ID: <AANLkTin_-bH09WK43DS9p0Kpp=7y6iHbLnUrCtOc6Qy5@mail.gmail.com> (raw)

Hello,

When I forbid memory overcommiting, malloc() returns 0 if can't
reserve memory, but in a cgroup it will always succeed, when it can
succeed when not in the group.
E.g. I've set 2 to overcommit_memory, limit is 10M: I can ask malloc
100M and it will not return any error (kernel is 2.6.32).
Is it expected behavior?
