Subject: [PATCH v2 1/1] fs/binfmt_elf_fdpic: fix error return code in load_elf_fdpic_binary()
Date: Thu, 15 Jul 2021 15:41:14 +0800	[thread overview]
Message-ID: <20210715074114.3246-2-thunder.leizhen@huawei.com> (raw)
In-Reply-To: <20210715074114.3246-1-thunder.leizhen@huawei.com>

When the call to create_elf_fdpic_tables() fails, the returned error code
should be propagated. However, we currently do not explicitly assign this
error code to 'retval'. As a result, 0 was incorrectly returned.

Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
