I don't know if this is the proper place to discuss this, but I am curious about the cause. Was it an issue with the way XFS is calling the allocator in a for(;;) loop when it does not get the expected result? Or was it an issue with the allocator itself not working in some obscure edge case? Or was it my .config, stretching the kernel ability to function in a bad way? -- You may reply to this email to add a comment.
