Pramod, thank you for reporting your environment.
(I got the report privately.)
After some code reading both kernel and glibc I guess glibc you are using
disables fadvise64 used in posix_fadvise. I hope we can detect it with
__NR_fadvise64 constant. The following patch terminates the tests if
__NR_fadvise64 is 0.
In other word this patch handles following output:
> posix_fadvise01 1 FAIL : unexpected returnd value - 38 : Function not
> implemented, advise 0 - expected 0
> <<<test_start>>>
> tag=posix_fadvise03_64 stime=2430
> cmdline=" posix_fadvise03_64"
> contacts=""
> analysis=exit
> initiation_status="ok"
> <<<test_output>>>
> posix_fadvise03 1 FAIL : call succeeded unexpectedly
I still don't understand why these calls are succeeded.
Could you tell me the name of distribution you are using?
Or could you give me the output of
$ strace POSIX_FADVISE03_64
Here POSIX_FADVISE03_64 stands for the complete path to the
executable of posix_fadvise03_64 test case file.
