[CRIU] [PATCH v5 0/4] c/r of file leases

[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 missing info about leases in proc/fd (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
