[PATCH 00/07] sysv SHM checkpoint/restart

[Oren Laadan]

This patchset adds support for IPC shared-memory. It applies on top
of c/r v14-rc2. Tested on x86_32 and verified with the test provided
in the userspace tools. 

Oren Laadan (7):
      ipc: allow allocation of an ipc object with desired identifier
      ipc: helpers to save and restore kern_ipc_perm structures
      sysvipc-shm: checkpoint
      sysvipc-shm: restart
      Infrastructure for work postponed to the end of checkpoint/restart
      sysvipc-shm: export interface from ipc/shm.c to delete ipc shm
      sysvipc-shm: correctly handle deleted (active) ipc shared memory
