Hi:
Is the message is $SUBJECT something to be concerned about or a bug ?
Yes that would be a bug.
Ok, I will check if I spot it again.
Looking at the code which generates this warning, there is a dump_stack() following which should certainly tell you who got it wrong.
?? the code I found only says:
lib/idr,c err:
printk(KERN_WARNING "ida_remove called for id=%d which is not allocated.\n", id);
dont see any dump_stack there,,,
You might have to
tweak /etc/rsyslog.conf to have them logged. They should be in "dmesg" already though.
Not using syslog, only the journal.
Right, it's not idr_remove() but ida_remove(). The dump_stack is issued only for the former, unfortunately.
I have sent a patch upstream, adding the missing call to dump_stack() after the warning in ida_remove(). I have also applied that patch to our Factory kernel. Cristian, I invite you to update to the next Factory kernel which builds (doesn't seem to be the case right now, unfortunately) so that you get the stack dump in the event the bug happens to you again. -- Jean Delvare Suse L3 -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org
