[PATCH OLK-6.6 1/1] cgroup/psi: add PSI_STATE_LAST for kabi reserve
by Chen Ridong 23 Sep '24

23 Sep '24

Offering: HULK hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IARWZ2 -------------------------------- Adding KABI_RESERVE for psi_stat_states results in redundant information being shown when running cat pressure.stat. Therefore, add PSI_STATE_LAST to maintain an unchanged KABI and eliminate the invalid information displayed in pressure.stat.
