[PATCH 0/2] mm/ksm: calculate ksm_process_profit more accurately
From: Longlong Xia
Date: Tue Jun 03 2025 - 23:18:16 EST
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!
