Subject: [PATCH v4 2/6] mm: add missing VM_FAULT_RESULT_TRACE name for VM_FAULT_COMPLETED
Date: Wed, 28 Jun 2023 00:17:56 -0700	[thread overview]
Message-ID: <20230628071800.544800-3-surenb@google.com> (raw)
In-Reply-To: <20230628071800.544800-1-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.
