[Bug 821603] Re: sysctl -p doesn't work on vm.dirty_background_bytes = 0

I have tried this now and it behaves like 0.


> Also, did you check that the value isn't getting overwritten by a later line in the same or a later config file in /etc/sysctl.d?

Yes, sysctl is even telling me that it wanted to apply 0:

root at ubuntu:~# sysctl -p
vm.dirty_background_bytes = 0
root at ubuntu:~# sysctl -a | grep 'vm\.dirty_background_bytes'
vm.dirty_background_bytes = 1048576

Title:
  sysctl -p doesn't work on vm.dirty_background_bytes = 0

Status in “procps” package in Ubuntu:
  New

Bug description:
  I'm using Ubuntu 11.10 dev. For example set vm.dirty_background_bytes to 1048676, execute "sysctl -p" and then check the value with "sysctl -a | grep 'vm\.'". vm.dirty_background_bytes is now set to 1048676 as expected. But if vm.dirty_background_bytes is now set to 0, "sysctl -p" is executed and the value is checked with "sysctl -a | grep 'vm\.'" it still shows 1048676 instead of 0.
