v2: fix problems pointed out by Dmitry Safonov <0x7f454c46 at gmail.com>
v3: fixes pointed out by Andrew Vagin <avagin at virtuozzo.com>
v4: move detection to separate function + minor improvements
v5-v7: handle parent's stats entry
v8: debuging for travis fail and couple of small fixes
v9: use inventory image instead of stats as stats are not designed to
hold restore critical data: revert old version so that new patches would
look cleaner, skip debugging patches as they are fine and leave
dump_uptime in stats file; also redo the pid-reuse to fix races.
Pavel Tikhomirov (10):
Revert "memory: don't use parent memdump if detected possible pid
reuse"
Revert "stats: add a helper to get stats of parent pre-dump"
Revert "stats: save uptime to know when dump had happened"
Revert "parse: add a helper to obtain an uptime"
parse: add a helper to obtain an uptime
inventory: save uptime to know when dump had happened
inventory: add a helper to get entry of parent pre-dump
memory: don't use parent memdump if detected possible pid reuse
zdtm/lib: add pre-dump-notify test flag
zdtm: check that pid-reuse does not break iterative memory dump
