Subject: [RFC PATCH v1.1 06/11] mm/damon/sysfs-schemes: kobject_del() scheme quota goal dirs
Date: Wed, 17 Jun 2026 07:48:00 -0700	[thread overview]
Message-ID: <20260617144807.91441-7-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 quota goal directories by adding kobject_del()
calls.

Fixes: 7f262da0a30d ("mm/damon/sysfs-schemes: implement files for scheme quota goals setup")
Cc: <stable@vger.kernel.org> # 6.8.x
