Subject: [PATCH 0/2] mm/ksm: calculate ksm_process_profit more accurately

During the KSM testing, it was observed that the sum of KSM profits 
for each process does not equal the general_profit.

The reason is general_profit_show() only considers ksm_pages_sharing,
whereas ksm_process_profit() accounts for both ksm_pages_sharing
and ksm_pages_shared for each process. By concentrating solely on 
ksm_pages_sharing, we can achieve a more accurate representation 
of actual profits.

Thanks for review and comments!
