After commit653d7825c1("dcssblk: mark DAX broken, remove FS_DAX_LIMITED support") moved the "select DAX" from config DCSSBLK to the new config DCSSBLK_DAX, randconfig tests could result in build errors like this: s390-linux-ld: drivers/s390/block/dcssblk.o: in function `dcssblk_shared_store': drivers/s390/block/dcssblk.c:417: undefined reference to `kill_dax' s390-linux-ld: drivers/s390/block/dcssblk.c:418: undefined reference to `put_dax' This is because it's now possible to have CONFIG_DCSSBLK=y, but CONFIG_DAX=m. Fix this by adding "depends on DAX || DAX=n" to config DCSSBLK, to make it explicit that we want either no DAX, or the same "y/m" for both config DAX and DCSSBLK, similar to config BLK_DEV_DM. This also requires removing the "select DAX" from config DCSSBLK_DAX, or else there would be a recursive dependency detected. DCSSBLK_DAX is marked as BROKEN at the moment, and won't work well with DAX anyway, so it doesn't really matter if it is selected.

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 reStructuredText 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.
