* BACKGROUND:
*
* Percpu refcounts are quite useful for performance, but if we blindly
- * converted all refcounts to percpu counters we'd waste quite a bit of memory
- * think about all the refcounts embedded in kobjects, files, etc. most of which
- * aren't used much.
+ * converted all refcounts to percpu counters we'd waste quite a bit of memory.
*
- * These start out as simple atomic counters - a little bigger than a bare
- * atomic_t, 16 bytes instead of 4 - but if we exceed some arbitrary number of
- * gets in one second, we then switch to percpu counters.
