Merge branch 'modules-next' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux
Pull module updates from Luis Chamberlain:
"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.
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."
