cgroup: don't use fread in read_cgroup_prop()
I think this version of code is a bit more readable. It doesn't do memcpy and doesn't allocate FILE. Everyone knows arguments for read(), but only a few of us know arguments for fread(). CID 73345 (#1 of 1): String not null terminated (STRING_NULL) 2. string_null_argument: Function fread does not terminate string *buf. [Note: The source code implementation of the function has been overridden by a builtin model.] Cc: Tycho Andersen <tycho.andersen@canonical.com> Signed-off-by:Andrey Vagin <avagin@openvz.org> Acked-by:
