From: Yixuan Cao <caoyixuan2019@email.szu.edu.cn> mainline inclusion from mainline-v5.18-rc1 commit 49e495a015e9cc127728b0f353a15d16da138fb8 category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I9GSSR Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... -------------------------------- I noticed a discrepancy between the usage method and the code logic. If we enable the -f option, it should be "Filter out the information of blocks whose memory has been released". Link: https://lkml.kernel.org/r/20220219143106.2805-1-caoyixuan2019@email.szu.edu....
