[PATCH v4 0/2] Fix warnings for RISC-V builds

From: Sean Chang

Date: Fri Feb 27 2026 - 10:28:52 EST


This series addresses several compiler warnings found when building the
kernel for RISC-V.

The first patch fixes unused variable warnings in the NFS client (including
nfs4proc and flexfilelayout) that occur in certain build configurations.

The second patch fixes a format-truncation warning in the MACB ethernet
driver by ensuring the snprintf output fits within the destination buffer.

v4:
- Refactor patch 1 to use no_printk() in sunrpc headers instead of marking
variables as __maybe_unused. This provides a cleaner, global fix and
enables compiler type checking.

v3:
- Expand commit descriptions to include technical details regarding macro
expansion, as requested by Andrew Lunn.
- Test the different platform, such as ARM, ARM64, X86_64.

v2:
- Split the original treewide patch into subsystem-specific commits.
- Added more detailed commit descriptions to satisfy checkpatch.

net: macb: use ethtool_sprintf to fill ethtool stats strings
