Subject: [PATCH 6/8] idr: Use xas_erase() in ida_destroy()
Date: Tue, 4 Feb 2020 15:25:12 +0100 [thread overview]
Message-ID: <20200204142514.15826-7-jack@suse.cz> (raw)
In-Reply-To: <20200204142514.15826-1-jack@suse.cz>
Explicitely clear marks (and set XA_MARK_FREE) in ida_destroy() by
calling xas_erase() instead of relying on xas_store() on implicitely
doing this.
