Subject: [PATCH v4 0/3] capabilities: Introduce CAP_CHECKPOINT_RESTORE

This is v4 of the 'Introduce CAP_CHECKPOINT_RESTORE' patchset. There
is only one change from v3 to address Jann's comment on patch 3/3

 (That is not necessarily true in the presence of LSMs like SELinux:
 You'd have to be able to FILE__EXECUTE_NO_TRANS the target executable
 according to the system's security policy.)

Nicolas updated the last patch (3/3). The first two patches are
unchanged from v3.

Adrian Reber (2):
  capabilities: Introduce CAP_CHECKPOINT_RESTORE
  selftests: add clone3() CAP_CHECKPOINT_RESTORE test

Nicolas Viennot (1):
  prctl: Allow ptrace capable processes to change /proc/self/exe
