[PATCH v3 0/2] selftests/mm: clean up build output and verbosity

From: Li Wang

Date: Wed Apr 22 2026 - 04:12:32 EST


Currently, the build process for the mm selftests is unnecessarily noisy.

First, it leaks raw compiler errors during the liburing feature probe if
the headers are missing, which is confusing since the build system already
handles this gracefully with a clear warning.

Second, the specific 32-bit and 64-bit compilation targets ignore the
standard kbuild verbosity settings, always printing their full compiler
commands even during a default quiet build.

Notes:
My email address has changed due to employment change.
Previous Signed-off-by was with <liwang@xxxxxxxxxx>.
Resent it after -rc1, as requested by Andrew.

V3:
- Nothing special but email change.

V2:

- Drop 2/4, 3/4 from v1 to v2, since Andrew wasn't able to confirm the
patch works for the rarely happening issue now, so I decided to just
hand on the process of the parallel issue.

- Refine the 4/4 patch only to hide compiler errors when missing liburing.
