kctune 11.23

I have tried to change kernel paramaet using kctune which will take affect in next reboot.

I have decided not to change that parameter, how can I roll back to old values?

kctune maxfiles_lim=nnnn

Re: kctune 11.23

kctune maxfiles_lim=old_value

However, maxfiles_lim changes are immediate, no reboot necessary.

# kctune maxfiles_lim=5000
