Hi, Bruce, This is the final revised version. Could you merge this patch into v6.12/base?
I haven't received feedback from the upstream mailing list yet, but I think this revision provides a solid solution. For a temporary page table intended for writing operations, maintaining write permissions is both necessary and acceptable, and following the orignal comment. The implementation shouldn't require extensive consideration of PTE read/write permissions from a userspace perspective. For details and context, please see the email thread: https://lore.kernel.org/all/[email protected]/ I welcome any feedback or alternative suggestions you might have.
