Hmm... I was trying to be careful not to break MSRV, but I think I accidentally had a Cargo.lock from a newer version hanging around which made me think it was higher than it really was. Will fix :) |

Fixes #124. Each line of
/proc/self/cgroupis assigned a version based on the value of the second field (it's always empty for cgroup2). If cgroups v1 and v2 are enabled at the same time, v1 is preferred (not sure if that's actually possible, but the rust standard library accounts for it). Chooses betweencpu.maxandcpu.cfs_period_us/cpu.cfs_quota_usbased on the detected version.
