Hi,
qemu test branch: https://git.kraxel.org/cgit/qemu/log/?h=sirius/udmabuf
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
- if (!shmem_mapping(file_inode(ubuf->filp)->i_mapping))
goto err_free_ubuf;Can/should we test here that the memfd has a locked down size here?
Makes sense. Suggested way to check that? unstatic memfd_get_seals() function (mm/shmem.c)? Or is there some better way?
Also which seals should we require? Is F_SEAL_SHRINK enough?
On that: Link to userspace patches/git tree using this would be nice.
See above.
cheers, Gerd
