* Increased coverage
  - ioctl_loop01 added LO_FLAGS_AUTOCLEAR flag coverage
  - timer_gettime01 added timer_gettime64() coverage
  - timer_settime{01,02} added timer_settime64() coverage
  - timerfd{01,04} added timerfd_gettime64() coverage
  - timerfd_gettime01 added timerfd_gettime64() coverage
  - timerfd_settime{01,02} added timerfd_gettime64() coverage
  - sched_rr_get_interval{01,02,03} added sched_rr_get_interval_time64() coverage
  - sched_rr_get_interval01 checks the return value against /proc/sys/kernel/sched_rr_timeslice_ms
  - io_pgetevents{01,02} added io_pgetevents_time64() coverage
  - ioctl_loop02 added LOOP_CONFIGURE test for LO_FLAGS_READ_ONLY
  - pidfd_open01 added check for CLOEXEC handling

  - msgsnd01 added check for msg_lspid and msg_stime
  - msgrcv01 added check for msg_lrpid and msg_rtime
  - msgrcv07 added more msgtyp tests
  - semop{01,02,03} added semtimedop() and semtimedop_time64() coverage
  - fanotify{14,16} added FAN_REPORT_DFID_NAME and FAN_REPORT_* coverage
  - fanotify09 added cases with subdirectory marks
  - fanotify10 added cets for FAN_REPORT_NAME and ignore mask
  - ioctl_loop07 added LOOP_CONFIGURE test for lo_sizelimit

* As you can see this release got the rest of the the 64bit timestamp
  testcases, 64bit timestamp syscalls should be reasonably covered now

* The quickhit runtest file was removed and replaced for quick integration
  tests with smoketest runtest file

* Additional 26 tests were converted to the new test library, significant part
  of these were cleaned up and rewritten SystemV IPC testcases

* LTP now includes VDSO parser and explicitly tests timer VDSO functions

* The backing files for a loop devices are now created by fallocate(), if
  possible, which speeds up loop device based tests quite a bit

* The build system was tweaked to produce much cleaner output,
  verbose output could be enabled by setting an environment variable V=1

+ The usual amount of fixes and cleanups.


NOTABLE CHANGES IN NETWORK TESTS
================================
brought to you by Petr Vorel

* remove RSH support (for legacy tests use SSH by default in $LTP_RSH)

* removed rsh, rcp, rlogin tests

* NFS: detect disabled UDP, expect it being disabled on v5.6+
       (NFS_DISABLE_UDP_SUPPORT is default y)

* TST_NET_RHOST_RUN_DEBUG=1 enables debugging

+ various fixes and updated docs
