Solution to compilation failures is to add fallback definition into ltp/include/lapi/mount.h (have a look at ltp/include/lapi/fcntl.h) and include it in the testcase source. That would make the testcase compile, but it may still fail when executed. To fix the execution we would need to do a runtime check if the kernel supports this flag, I guess that we would need to pass it only on newer kernels (we use tst_kvercmp() for that). -- Cyril Hrubis chru...@suse.cz ------------------------------------------------------------------------------ One dashboard for servers and applications across Physical-Virtual-Cloud Widest out-of-the-box monitoring support with 50+ applications Performance metrics, stats and reports that give you Actionable Insights Deep dive visibility with transaction tracing using APM Insight. http://ad.doubleclick.net/ddm/clk/290420510;117567292;y _______________________________________________ Ltp-list mailing list Ltp-list@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/ltp-list
