Merge tag 'modules-for-v5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux

Pull modules updates from Jessica Yu:
 "Summary of modules changes for the 5.11 merge window:

   - Fix a race condition between systemd/udev and the module loader.

     The module loader was sending a uevent before the module was fully
     initialized (i.e., before its init function has been called). This
     means udev can start processing the module uevent before the module
     has finished initializing, and some udev rules expect that the
     module has initialized already upon receiving the uevent.

     This resulted in some systemd mount units failing if udev processes
     the event faster than the module can finish init. This is fixed by
     delaying the uevent until after the module has called its init
     routine.

   - Make the linker array sections for kernel params and module version
     attributes more robust by switching to use the alignment of the
     type in question.

     Namely, linker section arrays will be constructed using the
     alignment required by the struct (using __alignof__()) as opposed
     to a specific value such as sizeof(void *) or sizeof(long). This is
     less likely to cause breakages should the size of the type ever
     change (Johan Hovold)

   - Fix module state inconsistency by setting it back to GOING when a
     module fails to load and is on its way out (Miroslav Benes)

   - Some comment and code cleanups (Sergey Shtylyov)"
