[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 I add little function which can replace timeval_valid,
because it is not universal enough to take both timeval and timespec.

Second patch stands for syscalls needed to opperate with timers.

In 3-7 patches: add structures, fd's, show functionality, parse proc.
Also there are parasite function to get time from timers.

In 8-11 patches: restore: read info from image, place it in allocated
mem and remap it in region which will be shared. And when injected,
start timers and set them.

In 12 patch modify tests for posix timers - use oneshot timers, and add
'holes'.

Thanks!
