• 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
  the 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
