Rationale: - ND_ROOT_PRESET is only set in a condition already marked unlikely - LOOKUP_IS_SCOPED already has unlikely on it, but inconsistently applied - set_root() only fails if there is a bug - most names are not empty (see !*s) - most of the time path_init() does not encounter LOOKUP_CACHED without LOOKUP_RCU - LOOKUP_IN_ROOT is a rarely seen flag Signed-off-by: Mateusz Guzik <mjguzik@gmail.com> Link: https://patch.msgid.link/20251105150630.756606-1-mjguzik@gmail.com Signed-off-by: Christian Brauner <brauner@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.
