Subject: [PATCH] livepatch: Add a missing newline character in klp_module_coming()
Date: Tue, 30 Aug 2022 19:28:55 +0800	[thread overview]
Message-ID: <20220830112855.749-1-thunder.leizhen@huawei.com> (raw)

The error message is not printed immediately because it does not end with
a newline character.

Before:
root@localhost:~# insmod vmlinux.ko
insmod: ERROR: could not insert module vmlinux.ko: Invalid parameters

After:
root@localhost:~# insmod vmlinux.ko
[   43.982558] livepatch: vmlinux.ko: invalid module name
insmod: ERROR: could not insert module vmlinux.ko: Invalid parameters

Fixes: dcf550e52f56 ("livepatch: Disallow vmlinux.ko")
