Not all architectures like ARM64 need to override the function. Move its declaration to kvm_dirty_ring.h to avoid the following compiling warning on ARM64 when the feature is enabled. arch/arm64/kvm/../../../virt/kvm/dirty_ring.c:14:12: \ warning: no previous prototype for 'kvm_cpu_dirty_log_size' \ [-Wmissing-prototypes] \ int __weak kvm_cpu_dirty_log_size(void) Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Gavin Shan <gshan@redhat.com> Reviewed-by: Peter Xu <peterx@redhat.com> Signed-off-by: Marc Zyngier <maz@kernel.org> Link: https://lore.kernel.org/r/20221110104914.31280-3-gshan@redhat.com
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.
