hulk inclusion category: cleanup bugzilla: https://atomgit.com/openeuler/kernel/issues/8423 -------------------------------- This commit replaces a hardcoded magic number used for the maximum length of scheduler class name strings with the named constant SCHED_CLASS_MAX_LENGTH. No functional change is introduced, this is a pure cleanup for better code hygiene.
