Subject: [PATCH v4 2/2] amdgpu: delete the "Failed to register MMU notifier" message
Date: Wed, 07 Jan 2026 21:31:15 +0100 [thread overview]
Message-ID: <20260107203230.880324802@debian4.vm> (raw)
In-Reply-To: <20260107203113.690118053@debian4.vm>
This error may happen if mm_take_all_locks was interrupted by a signal -
the userspace will retry an ioctl that returned -EINTR, so there is no
need to report it to the syslog.
Christian König suggested to remove this message at all, so let's do it.
