Add struct pid and use it everywhere. This struct contains two fields: pid and real_pid. real_pid is a pid outside of the target pid namespace. pid is in the target pid namespace Signed-off-by:

Checkpoint and restore do use fdtype_ops and file_desc_ops intensively so reorder pipes functions, this allow us to make them static and drop additional declarations. No func changes. Signed-off-by:

xemul: Why we haven't done this earlier? Because the pe entry contained the amount of bytes in the pipe and this value had to be calculated before we wrote this entry into the image. Now the pipe data is stored in another img file and we can happily split pe dump and pde dump into two calls. Signed-off-by:

v5: 1) make change directory messages supressed. v4: 1) Fixed apply conflicts. v3: 1) "crtools" goal dependences fixed. v2: 1) wrong "protobuf/tmp.pb-c.h" inclusion removed from cr-dump.c Without this patch "touch parasite.c" will lead to rebuild of the whole project. This patch also introduces "pie" goal as a subsystem. This will be usefull, when other subsystems will apper, because it allows to build them in parallel. "all" becomes default goal. This allows to skip deps inclusion for empty, "all", "zdtm" and "test-legacy" goals. Signed-off-by:

because they describes a process TREE. It's usefull, when we dump tasks from another pid namespace, because a real pid is got from parasite. In previous version we need to update pid in two places one is in a pstree_item and one is in a children array. A process tree will be necessery to restore sid and pgid, because we should add fake tasks in a tree. For example if a sesion leader is absent. v2: fix rollback actions v3: fix comments from Pavel Emelyanov * add macros for_each_pstree_item * and a few bugs Signed-off-by: -
