Subject: [PATCH v3 2/8] mm: add missing VM_FAULT_RESULT_TRACE name for VM_FAULT_COMPLETED
Date: Mon, 26 Jun 2023 21:23:15 -0700	[thread overview]
Message-ID: <20230627042321.1763765-3-surenb@google.com> (raw)
In-Reply-To: <20230627042321.1763765-1-surenb@google.com>

VM_FAULT_RESULT_TRACE should contain an element for every vm_fault_reason
to be used as flag_array inside trace_print_flags_seq(). The element
for VM_FAULT_COMPLETED is missing, add it.
