The summary of changes is as follows.. Generic changes:: - Added configure support [2]. - Check for lchmod filesystem support with create_file(..); for testcases that require lchmod, skip the testcase -- otherwise use chmod directly [1]. - Added Travis CI integration [2]. - Added utimensat testcases [1]. Linux support:: - Fixed Linux support to pass on later supported versions of Fedora/Ubuntu [2]. - Conditionally enable posix_fallocate(2) support [2]. OSX support:: - Fixed compilation on OSX [2]. - Added partial OSX support (the test run isn't fully green yet) [2]. MFC after: 2 months Obtained from: https://github.com/pjd/pjdfstest/tree/0.1 Relnotes: yes Submitted by: asomers [1], ngie [2] Tested with: UFS, ZFS
