'struct i2c_algorithm' are not modified in these drivers. Constifying this structure moves some data to a read-only section, so increase overall security, especially when the structure holds some function pointers. More over, dvb_usb_device_properties->i2c_algo seems to only be copied in i2c_adapter->algo, which is already a "const struct i2c_algorithm". This is done in dvb_usb_i2c_init() On a x86_64, with allmodconfig, as an example: Before: ====== text data bss dec hex filename 30571 5916 36 36523 8eab drivers/media/usb/dvb-usb/af9005.o After: ===== text data bss dec hex filename 30667 5852 36 36555 8ecb drivers/media/usb/dvb-usb/af9005.o Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
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.
