[PATCH] selftests/mm: fix uffd-stress help information

From: Rong Tao
Date: Mon Aug 14 2023 - 06:47:05 EST


From: Rong Tao <rongtao@xxxxxxxx>

commit 686a8bb72349("selftests/mm: split uffd tests into uffd-stress and
uffd-unit-tests") split uffd tests into uffd-stress and uffd-unit-tests,
obviously we need to modify the help information synchronously.

Also modify code indentation.
