[CRIU] [PATCH 0/9] cr_errno, v4

[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

v2, changed the way we trasfer cr_errno from children and fixed
    error codes
v3, atomic_cmpxchg used for cr_err
v4, use helpers to access cr_err and cr_errno

Ruslan Kuprieiev (9):
  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, v3
  cr-service: setup_opts_from_req: use single error exit point
  cr-service: set cr_errno to EBADRQC if set_opts_from_req fails
  service: add cr_errno to criu_resp and send cr_errno in it
  test: rpc: cr_errno, v3
  libcriu: add cr_errno support
  test:libcriu: add cr_errno test
