Subject: [PATCH 0/2] qnx4: Avoid confusing compiler about buffer lengths
Date: Fri, 17 Nov 2023 19:32:21 -0800 [thread overview]
Message-ID: <20231118032638.work.955-kees@kernel.org> (raw)
Hi,
This attempts to fix the issue Ronald Monthero found[1]. Avoids using a
too-short struct buffer when reading the string, by using the existing
struct union.
