PATCH 1/1 check: catch updated suspicious RCU usage message in _check_dmesg()

From: Eric Biggers <[email protected]>

In the v4.11 kernel, the suspicious RCU usage message uses the word "ERR" rather than "INFO". Update _check_dmesg to accept both versions.

Thanks! I updated the commit log a bit to refer to kernel commit 4d4f88fa235f ("lockdep: Make RCU suspicious-access splats use pr_err")

Thanks,
Eryu
