i´d like to acknowledge that this fixes the problem i had when creating loop-devices inside uml.
instead of crashing the whole uml, losetup now tells: ioctl: LOOP_SET_FD: Resource temporarily unavailable and dmesg: Apr 2 20:17:53 localhost udevd[641]: udev_event_run: fork of child failed: Resource temporarily unavailable Apr 2 20:17:54 localhost last message repeated 4 times Apr 2 20:17:54 localhost udevd-event[3014]: run_program: fork of '/lib/udev/udev_run_hotplugd' failed:Resource temporarily unavailable Apr 2 20:17:54 localhost udevd-event[3014]: run_program: fork of '/lib/udev/udev_run_devd' failed: Resource temporarily unavailable Apr 2 20:17:54 localhost udevd-event[3014]: run_program: fork of '/sbin/pam_console_apply' failed: Resource temporarily unavailable Apr 2 20:17:54 localhost udevd[641]: udev_event_run: fork of child failed: Resource temporarily unavailable so, this should be right behaviour now when running out of memory. regards roland ----- Original Message ----- From: "Jeff Dike" <[EMAIL PROTECTED]> To: "Andrew Morton" <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]> Cc: "LKML" <[email protected]>; "uml-devel" <[email protected]> Sent: Monday, April 02, 2007 6:50 PM Subject: [PATCH 4/4] UML - kernel_thread shouldn't panic > kernel_thread should just return an error value on do_fork failure, not > panic. > > Signed-off-by: Jeff Dike <[EMAIL PROTECTED]> > -- > arch/um/kernel/process.c | 2 -- > 1 file changed, 2 deletions(-) > > Index: linux-2.6.21-mm/arch/um/kernel/process.c > =================================================================== > --- linux-2.6.21-mm.orig/arch/um/kernel/process.c 2007-04-02 > 11:51:43.000000000 -0400 > +++ linux-2.6.21-mm/arch/um/kernel/process.c 2007-04-02 > 12:01:00.000000000 -0400 > @@ -97,8 +97,6 @@ int kernel_thread(int (*fn)(void *), voi > current->thread.request.u.thread.arg = arg; > pid = do_fork(CLONE_VM | CLONE_UNTRACED | flags, 0, > ¤t->thread.regs, 0, NULL, NULL); > - if(pid < 0) > - panic("do_fork failed in kernel_thread, errno = %d", pid); > return pid; > } > ------------------------------------------------------------------------- Take Surveys.
