Hi veerendra,
Thanks for patch. And apologies for delay as i could not review because
i was busy with some other stuffs.
Just have one Q: How this testcase ( pidns04.c ) is different from
pidns01.c which is already with LTP ?
>From my point of view it is quite similar. If some enhancement is
require we can modify pidns01.c itself. No need to add separate .c file.
And FYI, I am getting failure as below with latest kernel. Is it
expected behavior ?
