[PATCH OLK-6.6 v2 0/2]Support thp policy control per process
by Tong Tiangen 28 May '25

28 May '25

A tool and driver are added to control the thp policy per-process. Currently, only supports PMD size THP control. In the future, more functions can be supported based on this tool and driver. v2: modify openeuler_defconfig.
