Re: [LTP] [PATCH] check two possible pathes for cpuset

[CAI Q. <ca...@re...>]

> Is there a requirement that documents this behavior?
Garrett, there is one in the kernel doc,
http://lxr.linux.no/#linux+v2.6.37/Documentation/cgroups/cpusets.txt

"Note that for legacy reasons, the "cpuset" filesystem exists as a
wrapper around the cgroup filesystem.

The command

mount -t cpuset X /dev/cpuset

is equivalent to

mount -t cgroup -ocpuset,noprefix X /dev/cpuset"

However, I found this is not always case. In addition, there is an
direct implementation without cgroup, and I can't find any doc about
the behaviours of the prefix.
