Subject[PATCH] init/Kconfig: make CHECKPOINT_RESTORE select PROC_PAGE_MONITOR
Date
Checkpointing a process requires knowledge about the process memory layout
which is obtained from /proc/<pid>/smaps, /proc/<pid>/pagemap etc.
Make sure these interfaces are available only when
CONFIG_CHECKPOINT_RESTORE=y
