Subject: [PATCH] ubi: fastmap: fix inverted logic in seen selfcheck
Date: Wed, 23 Oct 2019 11:58:12 +0200 [thread overview]
Message-ID: <20191023095812.27470-1-s.hauer@pengutronix.de> (raw)
set_seen() sets the bit corresponding to the PEB number in the bitmap,
so when self_check_seen() wants to find PEBs that haven't been seen we
have to print the PEBs that have their bit cleared, not the ones which
have it set.
Fixes: 5d71afb00840 ("ubi: Use bitmaps in Fastmap self-check code")
