Subject: [LTP] [PATCH] lib: Introduce tst_path.h to consolidate system paths
Date: Fri, 1 May 2026 21:51:00 +0800 [thread overview]
Message-ID: <20260501135100.42278-1-li.wang@linux.dev> (raw)
Currently, definitions for various /proc and /sys paths are scattered
across multiple testcases and library files, often as hardcoded strings
or redundant macros.
This patch introduces a new common header, tst_path.h, to centralize
and standardize these path definitions. By unifying these macros, we
reduce code duplication, improve maintainability, and ensure consistent
path usage across the entire LTP codebase.
