From 9ea40db969115022335a553b4f6fe731dcd90c2a Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Thu, 8 May 2025 16:45:02 -0700 Subject: [PATCH] rcutorture: Print only one rtort_pipe_count splat The rcu_torture_writer() function scans the memory blocks after a stutter (or forced idle) interval, complaining about any that have not passed through ten grace periods since the start of the stutter interval. But one splat suffices, so this commit therefore stops at the first splat. Signed-off-by: Paul E.
