Subject: [PATCH 18/23] idr: Convert xas_store() to xas_store_noinit()
Date: Wed, 22 Apr 2020 17:02:51 +0200	[thread overview]
Message-ID: <20200422150256.23473-19-jack@suse.cz> (raw)
In-Reply-To: <20200422150256.23473-1-jack@suse.cz>

All remaining users of xas_store() store non-NULL entries so xas_store()
and xas_store_noinit() are equivalent. Replace xas_store() with
xas_store_noinit().
