Linux kernel source tree
0e0c52d603
Przemek Kitszel says: ==================== introduce DEFINE_FLEX() macro Add DEFINE_FLEX() macro, that helps on-stack allocation of structures with trailing flex array member. Expose __struct_size() macro which reads size of data allocated by DEFINE_FLEX(). Accompany new macros introduction with actual usage, in the ice driver - hence targeting for netdev tree. Obvious benefits include simpler resulting code, less heap usage, less error checking. Less obvious is the fact that compiler has more room to optimize, and as a whole, even with more stuff on the stack, we end up with overall better (smaller) report from bloat-o-meter: add/remove: 8/6 grow/shrink: 7/18 up/down: 2211/-2270 (-59) (individual results in each patch). ==================== Link: https://lore.kernel.org/r/20230912115937.1645707-1-przemyslaw.kitszel@intel.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

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.
