From 97f8f6d78999ab41d23cf5942d55ea3ad0ca4f3e Mon Sep 17 00:00:00 2001 From: Brian Behlendorf Date: Fri, 23 Apr 2010 15:55:02 -0700 Subject: [PATCH] Dump log from current process when required When dumping a debug log first check that it is safe to create a new thread and block waiting for it. If we are in an atomic context or irqs and disabled it is not safe to sleep and we must write out of the debug log from the current process. --- module/spl/spl-debug.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/module/spl/spl-debug.c b/module/spl/spl-debug.c index a3fcd74..0602a1a 100644 --- a/module/spl/spl-debug.c +++ b/module/spl/spl-debug.c @@ -1112,6 +1112,9 @@ void spl_debug_bug(char *file, const char *func, const int line, int flags) /* not reached */ } + if (in_atomic() || irqs_disabled()) + flags |= DL_NOTHREAD; + /* Ensure all debug pages and dumped by current cpu */ if (spl_debug_panic_on_bug) spl_panic_in_progress = 1; -- 2.40.0
