mainline inclusion from mainline-v5.15 commit 56eaeb10e2619081cc383febf6740a4c3e806777 category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I4G67J?from=project-issue CVE: NA
----------------------------------------------------------------------
xfstest generic/041 works with 3003 hardlinks. Because of this we raise hardlinks limit to 4000. There are no drawbacks or regressions. Theoretically we can raise all the way up to ffff, but there is no practical use for this.
