From cac79a39f200ef73ae7fc8a429ce2859ebb118d9 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Tue, 20 Feb 2018 15:25:11 -0800 Subject: [PATCH] tools/memory-model: Convert underscores to hyphens Typical cat-language code uses hyphens for word separators in identifiers, but several LKMM identifiers use underscores instead. This commit therefore converts underscores to hyphens in the .bell- and .cat-file identifiers corresponding to smp_mb__before_atomic(), smp_mb__after_atomic(), and smp_mb__after_spinlock().
