</span>Sorry if I wasn't clear. I've never actually written an Android.mk. I<br>
cross compiled using the Linaro (glibc based) prebuilt toolchain. Those<br>
steps are on the wiki:<br>

<br>
</span>Yes, the kernel was rebuilt with the CRIU-required options enabled. I've<br>
historically used mostly-vanilla upstream kernels with an Android<br>
userspace, but some of my colleagues used real Android kernels with the<br>
configuration changes applied. More options than just<br>
CONFIG_CHECKPOINT_RESTORE are required:<br>

<br>
(Using the wayback machine because I'm having trouble with <a href="http://criu.org" rel="noreferrer" target="_blank">criu.org</a> at<br>
the moment.)<br>
<br>
What version of Android and the kernel are you using? My recollection is<br>
that some of the older Android kernels required CRIU-related patches be<br>
backported, but maybe around Lollipop the kernel became new enough to<br>
not need backports.<br>

<br>
</span>What version of CRIU are you using? I see some recent map_files related<br>
changes in the git log.<br>
