Subject: [PATCH 37/56] ubi: Fix Fastmap's update_vol()
Date: Wed, 29 Aug 2018 14:19:53 +0200 [thread overview]
Message-ID: <1535545212-18871-38-git-send-email-t.remmet@phytec.de> (raw)
In-Reply-To: <1535545212-18871-1-git-send-email-t.remmet@phytec.de>
From: Richard Weinberger <richard@nod.at>
Usually Fastmap is free to consider every PEB in one of the pools
as newer than the existing PEB. Since PEBs in a pool are by definition
newer than everything else.
But update_vol() missed the case that a pool can contain more than
one candidate.
