This commit cause kernel panic when run threaded program. try /usr/src/tools/KSE/ksetest ----- Original Message ----- From: "Maxime Henrion" <mux@FreeBSD.org> To: <cvs-committers@FreeBSD.org>; <cvs-all@FreeBSD.org> Sent: Saturday, November 23, 2002 7:57 AM Subject: cvs commit: src/sys/kern kern_thread.c src/sys/sys proc.h src/sys/i386/i386 vm_machdep.c src/sys/alpha/alpha vm_machdep.c src/sys/ia64/ia64 vm_machdep.c src/sys/powerpc/powerpc vm_machdep.c src/sys/sparc64/sparc64 vm_machdep.c mux 2002/11/22 15:57:02 PST Modified files: sys/kern kern_thread.c sys/sys proc.h sys/i386/i386 vm_machdep.c sys/alpha/alpha vm_machdep.c sys/ia64/ia64 vm_machdep.c sys/powerpc/powerpc vm_machdep.c sys/sparc64/sparc64 vm_machdep.c Log: Under certain circumstances, we were calling kmem_free() from i386 cpu_thread_exit(). This resulted in a panic with WITNESS since we need to hold Giant to call kmem_free(), and we weren't helding it anymore in cpu_thread_exit(). We now do this from a new MD function, cpu_thread_dtor(), called by thread_dtor().
