Trying to boot without SYSFS, but with OF_DYNAMIC quickly results in a crash: [ 0.088460] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000070 [...] [ 0.103927] CPU: 1 PID: 1 Comm: swapper/0 Not tainted 5.14.0-rc3 #4179 [ 0.105810] Hardware name: linux,dummy-virt (DT) [ 0.107147] pstate: 80000005 (Nzcv daif -PAN -UAO -TCO BTYPE=--) [ 0.108876] pc : kernfs_find_and_get_ns+0x3c/0x7c [ 0.110244] lr : kernfs_find_and_get_ns+0x3c/0x7c [...] [ 0.134087] Call trace: [ 0.134800] kernfs_find_and_get_ns+0x3c/0x7c [ 0.136054] safe_name+0x4c/0xd0 [ 0.136994] __of_attach_node_sysfs+0xf8/0x124 [ 0.138287] of_core_init+0x90/0xfc [ 0.139296] driver_init+0x30/0x4c [ 0.140283] kernel_init_freeable+0x160/0x1b8 [ 0.141543] kernel_init+0x30/0x140 [ 0.142561] ret_from_fork+0x10/0x18 While not having sysfs isn't a very common option these days, it is still expected that such configuration would work. Paper over it by bailing out from __of_attach_node_sysfs() if CONFIG_SYSFS isn't enabled.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
