This patch set updates IPC checkpoint/restore support according to discussion of previous patch set named "IPC: message queue checkpoint support". What has been changed: 1) MSG_STEAL was replaced by MSG_PEEK_ALL (as suggested by Michael Kerrisk) 2) All checkpoint/restore code has been put under CONFIG_CHECKPOINT_RESTORE define. 3) Added return of ENOSYS in case of sys_msgrcv was called with MSG_PEEK_ALL flag, but kernel was compiled without checkpoint/restore support. 4) Test for support of SYSV IPC message queues checkpoint/restore added to the series. Test file: msgque.c
Michael, please, tell me, what I have to do (or provide) to update man page accordingly.
The following series consists of:
