[CRIU] Setting soft-dirty bit...

Hello,
I had a question about setting the soft-dirty bit. Can you please let me
know if there is a kernel API for setting this. Basically, from a driver, I
am pinning a page in the precess being pre-copied, writing some info to it
(from driver) and then unpinning the page. My question is that will this
automatically set the soft-dirty bit for the page? If not, is there an API
call for doing so?

Thanks,
Divjyot
