CLONE from pthread_create fails with ERESTARTNOINTR and application crashes

[Raghu Pv]

Hi WiIl,

Many Thanks for responding to my issue.

I am currently using 2.6.18.8 kernel for  armv4tl platform.

We are seeing this issue on our larger system codebase which happens
when pthread_create/clone call is interrupted by a signal.

I am currently working out to come up a sample code segment that can
reproduce the issue.

If you are aware of this issue in 2.6.18.8 kernel and if it is fixed
in subsequent commits please help me to find the relevant patches that
can resolve the problem.

I look forward for your response.

Thanks in advance.

Thanks,
Raghu
