Subject: [PATCH v2 1/4] fs/9p: remove unnecessary and overrestrictive check
Date: Tue, 18 Jul 2023 20:50:15 +0000 [thread overview]
Message-ID: <20230716-fixes-overly-restrictive-mmap-v2-1-147d6b93f699@kernel.org> (raw)
In-Reply-To: <20230716-fixes-overly-restrictive-mmap-v2-0-147d6b93f699@kernel.org>
This eliminates a check for shared that was overrestrictive and
duplicated a check in generic_file_readonly_mmap.
