Matthew Macy	7839c4b5e1	Update ZTS to work on FreeBSD ... Update the common ZTS scripts and individual test cases as needed in order to allow them to be run on FreeBSD. The high level goal is to provide compatibility wrappers whenever possible to minimize changes to individual test cases.

LOLi	99834d1950	Fix truncate(2) mtime and ctime handling ... On Linux, ftruncate(2) always changes the file timestamps, even if the file size is not changed. However, in case of a successfull truncate(2), the timestamps are updated only if the file size changes. This translates to the VFS calling the ZFS Posix Layer "setattr" function (zpl_setattr) with ATTR_MTIME and ATTR_CTIME unconditionally set on the iattr mask only when doing a ftruncate(2), while the truncate(2) is left to the filesystem implementation to be dealt with. This behaviour is consistent with POSIX:2004/SUSv3 specifications where there's no explicit requirement for file size changes to update the timestamps only for ftruncate(2): http://pubs.opengroup.org/onlinepubs/009695399/functions/truncate.html http://pubs.opengroup.org/onlinepubs/009695399/functions/ftruncate.html This has been later updated in POSIX:2008/SUSv4 where, for both truncate(2)/ftruncate(2), there's no mention of this size change requirement: http://austingroupbugs.net/view.php?id=489 http://pubs.opengroup.org/onlinepubs/9699919799/functions/truncate.html http://pubs.opengroup.org/onlinepubs/9699919799/functions/ftruncate.html Unfortunately the Linux VFS is still calling into the ZPL without ATTR_MTIME/ATTR_CTIME set in the truncate(2) case: we fix this by explicitly updating the timestamps when detecting the ATTR_SIZE bit, which is always set in do_truncate(), on the iattr mask.
