r272057:

  Import pjdfstest from ^/vendor/pjdfstest/abf03c3a47745d4521b0e4aa141317553ca48f91

  - Remove tools/regression/pjdfstest
  - Add upgrade directions for contrib/pjdfstest
  - Add a note to UPDATING for the move (the reachover Makefiles are coming
    soon)

  Functional differences:
  - ftruncate testcases are added from upstream (github)

  Non-functional differences:
  - The copyright for the project has been updated to 2012
  - pjd's contact information has been updated

  Discussed with: -testing, jmmv, pjd
  Sponsored by: EMC / Isilon Storage Division

r272083:

  Expect ELOOP on Darwin/Linux with "O_NOFOLLOW was specified and the target is a
  symbolic link" case. Assume EMLINK on the rest of the OSes (FreeBSD, Solaris,
  etc)

  Sponsored by: EMC / Isilon Storage Division

r272084:

  Fix the executed testplan count

  Sponsored by: EMC / Isilon Storage Division

r272087:

  Increase the memory disk size in the following testcases to avoid mount
  failures, which would cause cascade failures in the rest of the test
  run:

  link/15.t, open/19.t, mkdir/11.t, mkfifo/11.t, symlink/11.t

  Fail quickly in all of the testcases if mdconfig, mount, umount, etc
  fails to avoid issues similar to this in the future

r274016:

  Integrate pjdfstest test suite execution into kyua

  pjdfstest execution is opt-in and must be done as root due to some of the
  assumptions made by the test suite and lack of error checking in the non-root
  case

  A description of how to execute pjdfstest with kyua is provided in
  share/pjdfstest/README

  Phabric: D824 (an earlier prototype patch)

+This document contains a collection of notes specific to the import
+of pjdfstest into head.  These notes are built on the instructions in
+the FreeBSD Subversion Primer that detail how to deal with vendor
+branches and you are supposed to follow those:
+
+	http://www.freebsd.org/doc/en/articles/committers-guide/subversion-primer.html
+
+The pjdfstest source code is hosted on GitHub:
+
+	https://github.com/pjd/pjdfstest
+
+and is imported into the pjdfstest vendor branch (see base/vendor/pjdfstest/).
+
+To merge the vendor branch into head do something like this:
+
+	cd .../base/head/contrib/pjdfstest
+	svn merge --accept=postpone \
+	    svn+ssh://svn.freebsd.org/base/vendor/pjdfstest/dist .
+
+and resolve any conflicts that may arise at this point.
+
+Lastly, with the list of old and new files in this import, make sure
+to update the reachover Makefiles accordingly.

+
+Few notes on how to use pjdfstest in short steps:
+
+	# cd pjdfstest
+	# vi tests/conf
+	Change 'fs' to file system type you want to test (UFS or ZFS).
+	# vi Makefile
+	You need to manually tweak few things by editing CFLAGS lines
+	at the top of the file.
+	# make
+	It will compile pjdfstest utility which is used by regression tests.
+	# cd /path/to/file/system/you/want/to/test/
+	# prove -r /path/to/pjdfstest/tests
+
+That's all. Enjoy.
+
+Currently supported operating systems: FreeBSD, Solaris.
+Currently supported file system types: UFS, ZFS.
