We only use the last pid from the list in NSpid entry (from /proc/<pid>/fdinfo/<pidfd>) while restoring pidfds. The last pid refers to the pid of the process in the most deeply nested pid namespace. Since CRIU does not currently support nested pid namespaces, this entry is the one we want. After Linux 6.9, inode numbers can be used to compare pidfds. pidfds referring to the same process will have the same inode numbers. We use inode numbers to restore pidfds that point to dead processes. Signed-off-by: Bhavik Sachdev <b.sachdev1904@gmail.com>
