To get anything of that kind you would need to have a kernel thread open a file on such fs, do IO and fput() it, then have something attempt to unlink() it and fail with EBUSY due to fput() being delayed. If that something is *not* the same kernel thread, it's already racy - after all, if that unlink() happens while the kernel thread does IO, we are going to get what we are going to get. And if it is the same thread... What would it be? knfsd? Exporting a filesystem with possible-EBUSY-on-unlink? I don't see any exportable examples of that... -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
