No, it just clears that particular statistic.

On a semi-related topic, it would have been nice to isolate all statistic 
files to its own directory: /sys/kernel/slab/kmalloc-256/stats/..., for 
example.  It would have made collecting (and now clearing) all statistics 
much easier since userspace wouldn't need a predefined list of stat file 
names to scan.  I wonder if Pekka would allow them to be moved...
