Subject: [PATCH 03/10] resource: Rename 'tmp' variable to 'full_avail'
Date: Tue, 24 Mar 2026 18:56:26 +0200 [thread overview]
Message-ID: <20260324165633.4583-4-ilpo.jarvinen@linux.intel.com> (raw)
In-Reply-To: <20260324165633.4583-1-ilpo.jarvinen@linux.intel.com>
__find_resource_space() has variable called 'tmp'. Rename it to
'full_avail' to better indicate its purpose.
