Subject: [PATCH v4 05/10] loop: Remove figure_loop_size()
Date: Wed, 29 Apr 2020 16:03:36 +0200	[thread overview]
Message-ID: <20200429140341.13294-6-maco@android.com> (raw)
In-Reply-To: <20200429140341.13294-1-maco@android.com>

This function was now only used by loop_set_capacity(). Just open code
the remaining code in the caller instead.
