[CRIU] [PATCH 0/8] don't use wrong pagemap (from other task) on pid reuse

[Pavel Tikhomirov]

https://jira.sw.ru/browse/PSBM-67502

Pavel Tikhomirov (8):
  parse: add a helper to obtain an uptime
  stats: save uptime to know when dump had happened
  stats: add a helper to get stats of parent pre-dump
  memory: don't use parent memdump if detected possible pid reuse
  zdtm/lib/arch: add atomic_cmpxchg
  zdtm/lib: add futex_cmpxchg and futex_cmpxchg_and_wake
  zdtm/lib: add test_waitpre so that test knows about predump iters
  zdtm: check that pid-reuse does not break iterative memory dump
