Red Hat Bugzilla – Bug 443823
ionice.1 doesn't to reflect idle class changes in 2.6.25
Last modified: 2008-04-28 06:46:26 EDT
Description of problem:
$ ionice -c3 :
ioprio_set: Operation not permitted
Version-Release number of selected component (if applicable):
These don't work:
2.6.25 in Fedora works fine.
Actually this is documented in ionice(1) manual:
Idle. A program running with idle io priority will only get disk time
when no other program has asked for disk io for a defined grace period. The
idle io processes on normal system activity should be zero. This
scheduling class does not take a priority argument. This scheduling class is
for an ordinary (i.e., non-root) user.
Adding Karel to Cc:, since he maintains package that contains this manual page,
and IIRC he's also upstream for it, so he should probably adjust the manual page
to reflect the fact that at least in 2.6.25 the situation is different.
Due to the merging of a variant of http://lwn.net/Articles/266256/ for 2.6.25
We'll pick this up soon when we rebase F8's kernel.
Uh, not really a kernel bug.
The man page updated in F8, F9 and upstream git tree. Thanks!
