hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ICPMAC -------------------------------- Change the permissions of /proc/pressure/stat from 0666 to 0444. /proc/pressure/stat is read only now, therefore, there is no need to give the write permission to /proc/pressure/stat.
