[CRIU] [PATCH v4 0/4] file leases support

[Pavel Begunkov]

The patchset adds full support of file leases:
- procfs parsing changes
- Restoring of file leases. In case of broken leases it breaks
established lease with open syscall.
- Workaround inane 'broken lease type' (always 'READ') in procfs.
- Logic to support old kernels (v4.0 or older)
- zdtm tests

Pavel Begunkov (4):
  locks: Add c/r of non broken leases (kernel>=v4.1)
  locks: Add c/r of breaking leases (kernel>=v4.1)
  locks: Add leases c/r for kernels v4.0 and older
  zdtm: Add file lease tests
