[PATCH] check: catch updated suspicious RCU usage message in _check_dmesg()

[Date Prev] [Date Next] [Thread Prev] [Thread Next] [Date Index] [Thread Index]



From: Eric Biggers <ebiggers@xxxxxxxxxx>

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