Subject: [PATCH v2 2/6] mm: Add a leading 0 to the VM_FAULT_* types
Date: Tue, 14 Mar 2023 20:03:55 -0700 [thread overview]
Message-ID: <20230315030359.14162-3-palmer@rivosinc.com> (raw)
In-Reply-To: <20230315030359.14162-1-palmer@rivosinc.com>
The next patch will add enough codes to need another character, this
adds the 0 to all the existing codes to keep alignment.
