According to the manual the kcmp system call appeared in kernel 3.5
but SUSE kernels do not enable CONFIG_CHECKPOINT_RESTORE (kernel:head
zgrep CHECKPOINT_RESTORE /proc/config.gz
# CONFIG_CHECKPOINT_RESTORE is not set
Is there a reason why it is disabled ?
This comes from:
Author: Jeff Mahoney <jeffm(a)suse.com>
Date: Tue Feb 7 12:12:40 2012 -0500
- Update to 3.3-rc2.
- Eliminated 5 patches.
- Xen is disabled.
So I don't think it was disabled on purpose, rather
CONFIG_CHECKPOINT_RESTORE received its default value, which is n.
Furthermore, CHECKPOINT_RESTORE depends on EXPERT, which is not set on
most of our kernels.
What do you need this for?
I am a curious bastard :-) was exploring around when I read this
, wrote some little test and figured
out that this feature was disabled in openSUSE kernels.
The first thing that came to my mind is that it might be useful to
extend systemd with this functionality.. (systemctl checkpoint
blabla.service or similar) ;)
