Subject: Claude review: drm/xe/xe_pagefault: Disallow writes to read-only VMAs
Date: Tue, 24 Feb 2026 10:00:00 +1000 [thread overview]
Message-ID: <review-patch1-20260223172120.98961-7-jonathan.cavitt@intel.com> (raw)
In-Reply-To: <20260223172120.98961-7-jonathan.cavitt@intel.com>
Patch Review
This is a straightforward bugfix. The check is placed correctly after the VMA lookup:
> + if (xe_vma_read_only(vma) &&
> + pf->consumer.access_type != XE_PAGEFAULT_ACCESS_TYPE_READ) {
> + err = -EPERM;
> + goto unlock_vm;
> + }
This correctly rejects both write and atomic access to read-only VMAs. The `goto unlock_vm` follows the established error path in `xe_pagefault_service`. The `Fixes:` tag is appropriate. No issues found.
