Jakub Kicinski says: ==================== tools: ynl-gen: split presence metadata The presence metadata indicates whether given attribute was/should be added to the Netlink message. We have 3 types of such metadata: - bit presence for simple values like integers, - len presence for variable size attrs, like binary and strings, - count for arrays. Previously this information was spread around with first two types living in a dedicated sub-struct called _present. The counts resided directly in the main struct with an n_ prefix. Reshuffle these an uniformly store them in dedicated sub-structs. The immediate motivation is that current scheme causes name collisions for TC. ==================== Link: https://patch.msgid.link/20250505165208.248049-1-kuba@kernel.org 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 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.
