[CRIU] [PATCH 00/12] posix-timer: Add posix timers to criu

[Pavel Tikhomirov]

Hi,

In this patch I want to add posix timers dump/restore to criu.

In first patch stands for syscalls needed to opperate with timers.

In 2-6 patches: add structures, fd's, show functionality, parse proc.
Also there are parasite function to get time from timers.

In 7-10 patches: restore: read info from image, sort by timer_id, 
place it in allocated mem and remap it in region which will be shared.
And when injected, start timers and set them.

In 11-12 patch modify tests for posix timers - add 'holes' check, and
add macros which excludes periodic test.

Thanks!
