 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)
