From b930ff84f3072df7ab3b0f1cd3a8bb5d02ec4dec Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Wed, 6 Aug 2025 15:59:32 -0700 Subject: [PATCH] torture: Announce kernel boot status at torture-test startup Sometimes a given system takes surprisingly long to boot, for example, in one recent case, 70 seconds instead of three seconds. It would be good to fix these slow-boot issues, but it would also be good for the torture tests to announce that the system was still booting at the start of the test. Especially for tests that have a greater probability of false positives when run in the single-CPU boot-time environment. Yes, those tests should defend themselves, but we should also make this situation easier to diagnose. This commit therefore causes torture_print_module_parms() to print "still booting" at the end of its printk() that dumps out the values of its module parameters. Signed-off-by: Paul E.
