I have got no other explanation. Kernel security module apparmor itself got deactivated within the kernel b= y my boot-parameters "secure=3Dnone" and "apparmor=3Dnone". After tor and firejail version got changed from OpenSuSE 15.X to mga7, suc= h root-processes did not get activated! Now everything works fine! But I still awaint your patches for kernel-5.4.134... Regards Andreas St=F6wing, M=F6nchengladbach =2D----------------------- Back to my e-mail refering to kernel 5.4.134 (pclos) The unwanted, highly activated root-processes by tor (pclos, mga7) are kworker/u2:1-kcryptd/253:2 (escpecially this one, CPU: > 10%) kworker/0:1H-kblockd dmcrypt_write/2 jbd2/dm2--8 This occurs since kernel around 5.4.130. Please patch the kernel-5.4 to prevent it in future! Regards, Andreas St=F6wing Hi, This is the friendly email-bot of Greg Kroah-Hartman's inbox. I've detected that you have sent him a direct question that might be better sent to a public mailing list which is much faster in responding to questions than Greg normally is. Please try asking one of the following mailing lists for your questions: For udev and hotplug related questions, please ask on the linux-hotplug@vger.kernel.org mailing list For USB related questions, please ask on the linux-usb@vger.kernel.org mailing list For PCI related questions, please ask on the linux-pci@vger.kernel.org or linux-kernel@vger.kernel.org mailing lists For serial and tty related questions, please ask on the linux-serial@vger.kernel.org mailing list. For staging tree related questions, please ask on the devel@linuxdriverproject.org mailing list. For general kernel related questions, please ask on the kernelnewbies@nl.linux.org or linux-kernel@vger.kernel.org mailing lists, depending on the type of question. More basic, beginner questions are better asked on the kernelnewbies list, after reading the wiki at www.kernelnewbies.org. For Linux stable and longterm kernel release questions or patches to be included in the stable or longterm kernel trees, please email stable@vger.kernel.org and Cc: the linux-kernel@vger.kernel.org mailing list so all of the stable kernel developers can be notified. Also please read Documentation/process/stable-kernel-rules.rst in the Linux kernel tree for the proper procedure to get patches accepted into the stable or longterm kernel releases. If you really want to ask Greg the question, please read the following two links as to why emailing a single person directly is usually not a good thing, and causes extra work on a single person: http://www.arm.linux.org.uk/news/?newsitem=3D11 http://www.eyrie.org/~eagle/faqs/questions.html After reading those messages, and you still feel that you want to email Greg instead of posting on a mailing list, then resend your message within 24 hours and it will go through to him. But be forewarned, his email inbox currently looks like: 912 messages in /home/greg/mail/INBOX/ so it might be a while before he gets to the message. Thank you for your understanding. The email triggering this response has been automatically discarded. thanks, greg k-h's email bot
