Sounds good; thanks!
(I would argue 4 and 5 are also bug fixes, 6 is already Acked by hch and
you, and 7 is a logical follow-up to 6, but I get your point.)
James, Luis, Mimi, and Jessica, the bulk of these patches are LSM,
firmware, IMA, and modules. How does this all look to you? And KP,
you'd mentioned privately that you were interested in being able to
use the new kernel_post_load_data LSM hook for better visibility into
non-file-backed blob loading.
Thanks!
