Recursive loops with module loading were previously handled in kmod by restricting the number of modprobe calls to 50 and if that limit was breached request_module() would return an error and a user would see the following on their kernel dmesg: request_module: runaway loop modprobe binfmt-464c Starting init:/sbin/init exists but couldn't execute it (error -8) This issue could happen for instance when a 64-bit kernel boots a 32-bit userspace on some architectures and has no 32-bit binary format hanlders. This is visible, for instance, when a CONFIG_MODULES enabled 64-bit MIPS kernel boots a into o32 root filesystem and the binfmt handler for o32 binaries is not built-in. After commit |

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
