[LTP] [PATCH 0/3] tst_kconfig: automatic module load/unload for CONFIG_*=m

[Li Wang <li.wang@linux.dev>]

Tests that depend on a config set to =m currently load the module
themselves, and may fail with misleading errors when it is missing,
e.g. bind() returning EADDRNOTAVAIL for AF_VSOCK without vsock_loopback.

This series makes tst_kconfig record the module for every
config_module_maps[] entry seen as =m, load them once the kernel
config check passes, and unload them at cleanup time.

Li Wang (3):
  tst_kconfig: load and unload kernel modules for CONFIG_*=m
  tst_kconfig: add module mappings for vsock/vsock_loopback
  testcases: drop manual tst_modprobe() now handled by tst_kconfig
