CKI KWF Bot 0e1f1139b6 Merge: mm/damon/sysfs: cleanup attrs subdirs on context dir setup failure 
MR: https://gitlab.com/redhat/rhel/src/kernel/rhel-9/-/merge_requests/5669

JIRA: https://issues.redhat.com/browse/RHEL-150478
CVE: CVE-2026-23144

This patch is a backport of the following upstream commit:
commit 9814cc832b88bd040fc2a1817c2b5469d0f7e862
Author: SeongJae Park <sj@kernel.org>
Date:   Wed Dec 24 18:30:35 2025 -0800

    mm/damon/sysfs: cleanup attrs subdirs on context dir setup failure

    When a context DAMON sysfs directory setup is failed after setup of attrs/
    directory, subdirectories of attrs/ directory are not cleaned up.  As a
    result, DAMON sysfs interface is nearly broken until the system reboots,
    and the memory for the unremoved directory is leaked.

    Cleanup the directories under such failures.
