[Bug 821610] Re: ionice doesn't nice the complete writing process

[Sworddragon]

** Description changed:

  I'm using Ubuntu 11.10 dev. I'm starting apache with the command "chrt
  -i 0 ionice -c 3 /usr/sbin/apache2ctl". On my system is full data
  journaling enabled. Theoretically if apache or a child process from
  apache is writing something to the disk it shouldn't affect any other
- applications like games because apache has the lowest cpu an I/O
+ applications like games because apache has the lowest cpu and I/O
  priority possible. But sometimes a child process from apache is writing
  a lot to my disk and I can't do much at this time anymore. If I play a
  game it is freezing every second and unplayable. If I disable full data
  journaling it is much better. This is why I think the [jdb2/sda1-8]
  process doesn't inherit the nice/ionice from the writing process.
