Subject: [RFC PATCH v1.1 03/11] mm/damon/sysfs-schemes: kobject_del() scheme dirs
Date: Wed, 17 Jun 2026 07:47:57 -0700 [thread overview]
Message-ID: <20260617144807.91441-4-sj@kernel.org> (raw)
In-Reply-To: <20260617144807.91441-1-sj@kernel.org>
On CONFIG_DEBUG_KOBJECT_RELEASE enabled kernel, lack of kobject_del()
could cause directories creation failures due to the name conflicts. Fix
those issues for scheme directories by adding kobject_del() calls.
Fixes: 7e84b1f8212a ("mm/damon/sysfs: support DAMON-based Operation Schemes")
Cc: <stable@vger.kernel.org> # 5.18.x
