modules changes for v5.17-rc1
The biggest change here is in-kernel support for module decompression.
This change is being made to help support LSMs like LoadPin as otherwise
it loses link between the source of kernel module on the disk and binary
blob that is being loaded into the kernel.
kmod decompression is still done by userspace even with this is done,
both because there are no measurable gains in not doing so and as it
adds a secondary extra check for validating the module before loading it
into the kernel.
Although this change was only merged on January 11th, the patches have
been being reviewed since early december. There was at least one fix
already found for it and merged.
The rest of the changes are minor, the only other change worth mentionin
there is Jessica Yu is now bowing out of maintenance of modules as she's
taking a break from work.
While there were other changes posted for modules, those have not yet
received much review of testing so I'm not yet comfortable in merging
any of those changes yet.
