Description James Antill 2006-12-04 13:45:43 EST
Description of problem:

 SuS3 says:

The nice value set with setpriority() shall be applied to the process. If the
process is multi-threaded, the nice value shall affect all system scope threads
in the process.

...from http://www.opengroup.org/onlinepubs/009695399/functions/setpriority.html

 However this doesn't happen, the kernel just changes the priority of a single
task. I saw this with beagled-helper.

Version-Release number of selected component (if applicable):

% uname -a
Linux code.and.org 2.6.18-1.2849.fc6 #1 SMP Fri Nov 10 12:45:28 EST 2006 i686
athlon i386 GNU/Linux

How reproducible:

Steps to Reproduce:
1. Use renice command on multi-threaded application.

(This is a mass-update to all current FC6 kernel bugs in NEW state)


I'm reviewing this bug list as part of the kernel bug triage project, an attempt
to isolate current bugs in the Fedora kernel.


I am CC'ing myself to this bug, however this version of Fedora is no longer

Please attempt to reproduce this bug with a current version of Fedora (presently
Fedora 8). If the bug no longer exists, please close the bug or I'll do so in a
few days if there is no further information lodged.

Thanks for using Fedora!
