[CRIU] [PATCH 00/14] Initial support of shared descriptor tables (v4)

[Andrey Vagin]

Currently crtools supports a case when childen are shared fd table
with parent.

v2: cosmetic fixes according with Pavel's comments
v3: don't move ids from core to pstree
v4: save fdinfo per id instead of pid
    save ids in a separate image file
v5: rework service fd name-spaces one more time

Andrey Vagin (14):
  zdtm: test shared file tables
  mntns: close_proc before clean up mounts
  util: clone service descriptors, if fd tables are shared for tasks
    (v3)
  crtools: add ability to create and close a service fd
  crtools: don't use global variables for saving service fds
  crtools: put kobj-ids into separate image file
  dump: save ids on pstree_item
  pstree: allocate fdt shared data
  files: close_old_fds before forking children
  files: pass a file descriptor on an fdinfo image instead of cr_fdset
  files: dump fdinfo per files_id instead of pid (v2)
  lock: add futex_inc_and_wake and futex_wait_while_lt
  restore: restore pocesses which share one fdtable (v4)
  zdtm.sh: add fdt_shared to the list
