From b167158395e9238de99c1b6e5dac4f7394341df5 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Niklas=20S=C3=B6derlund?= Date: Wed, 4 Mar 2020 23:54:08 +0100 Subject: libcamera: V4L2BufferCache: Check for hot hit first MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Check for a hot cache hit before updating which buffer is best to evict in case no hot hit is found. This doesn't change the behaviour, but follows a more logical flow.
