Fix it by conditionalizing the per-cpu area allocation and usage on the size of the per-cpu struct. ---------------------------------------------------------------- JP Kobryn (1): cgroup: adjust criteria for rstat subsystem cpu lock access kernel/cgroup/rstat.c | 25 ++++++++++++++++--------- 1 file changed, 16 insertions(+), 9 deletions(-) -- tejun
