  module: delay kobject uevent until after module init call (2020-12-09 09:42:47 +0100)

----------------------------------------------------------------
Modules updates for v5.11

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 (from
  Johan Hovold)

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

- Some comment and code cleanups (from Sergey Shtylyov)
