Hi Christian Brauner:
Could we change the changelog as below, it maybe more reasonable
fs: Use percpu_counter_sum_positive in proc_nr_files
The centralized value of percpu counter can be really grossly inaccurate
as CPU count increases. and proc_nr_files is only accessed when reading
proc file, not a hot path, so use percpu_counter_sum_positive in it, to make
/proc/sys/fs/file-nr more accurate
thanks
