Vaibhav Nagarnaik d7ec4bfed6 ring-buffer: Set __GFP_NORETRY flag for ring buffer allocating process ... The tracing ring buffer is allocated from kernel memory. While allocating a large chunk of memory, OOM might happen which destabilizes the system. Thus random processes might get killed during the allocation. This patch adds __GFP_NORETRY flag to the ring buffer allocation calls to make it fail more gracefully if the system will not be able to complete the allocation request.
