Subject: selftests/mm: fix uffd-stress unused function warning
Date: Thu, 1 Jun 2023 18:33:47 -0700
Patch series "A minor flurry of selftest/mm fixes".
It turned out that an even dozen patches were required in order to get the
selftests building cleanly, and all running, once again. I made it worse on
myself by insisting on using clang, which seems to uncover a few more warnings
than gcc these days.
This patch (of 12):
uffd_minor_feature() was unused. Remove it in order to fix the associated
clang build warning.
