[CRIU] [PATCH 0/8] cr_errno, v2

[Ruslan Kuprieiev]

Currently our RPC doesn't provide almost any info
about failed request. Lets add first 4 most common
errors to be reported by service. These are:
  Process with such pid already exists(Pid do not match expected)
  No process with such pid
  Bad opts
  Invalid request

v2, changed the way we trasfer cr_errno from children and fixed
    error codes

Ruslan Kuprieiev (8):
  cr-errno: initial commit
  util: set cr_errno to ESRCH if no PID dir in proc
  cr-restore: set cr_error to EEXIST if such pid already exists, v2
  cr-service: setup_opts_from_req: use single error exit point
  cr-service: set cr_errno to EBADRQC if set_opts_from_req fails
  cr-service: set cr_errno to ENOTSUP if request is invalid
  service: add cr_errno to criu_resp and send cr_errno in it
  test: rpc: cr_errno, v2
