Subject: [PATCH 17/23] idr: Use xas_erase() in ida_free()
Date: Wed, 22 Apr 2020 17:02:50 +0200	[thread overview]
Message-ID: <20200422150256.23473-18-jack@suse.cz> (raw)
In-Reply-To: <20200422150256.23473-1-jack@suse.cz>

Explicitely clear marks in ida_free() by calling xas_erase() instead of
relying on xas_store() on implicitely doing this.
