[PATCH v2 0/4] Add modules.builtin.modinfo support

[Alexey Gladkov <gladkov.alexey@gmail.com>]

The kernel since version v5.2-rc1 exports information about built-in
modules in the modules.builtin.modinfo. Now, kmod can show complete information
about the built-in modules as well as about external modules. Also kmod can
understand aliases of built-in modules.

Before:

$ modinfo block-major-9-1
modinfo: ERROR: Module block-major-9-1 not found.

After:

$ modinfo block-major-9-1
name:           md_mod
filename:       (builtin)
alias:          block-major-9-*
alias:          md
description:    MD RAID framework
license:        GPL
parm:           start_dirty_degraded:int
parm:           create_on_open:bool

v2:

* Don't use kmod_file() to parse modules.builtin.modinfo. Instead, parser reads
the file into the buffer by chunks, which reduces the amount of memory.

Alexey Gladkov (4):
  libkmod: Add parser for modules.builtin.modinfo
  libkmod: Add function to get list of built-in modules
  Lookup aliases in the modules.builtin.modinfo
  modinfo: Show information about built-in modules
