Subject: [PATCH 2/6] bitmap: test bitmap_parse() with an illegal character before 8 hex digits
Date: Fri, 25 Sep 2026 15:53:03 +0530	[thread overview]
Message-ID: <20260925102307.49513-3-jain.sm@gmail.com> (raw)
In-Reply-To: <20260925102307.49513-1-jain.sm@gmail.com>

Add bitmap_parse() cases where an illegal character directly precedes a
chunk of eight hex digits.  These were accepted before the previous
patch and must return -EINVAL.
