Linux kernel source tree
76a53de6f7
audit_alloc_mark() and audit_get_nd() both need to perform a path lookup getting the parent dentry (which must exist) and the final target (following a LAST_NORM name) which sometimes doesn't need to exist. They don't need the parent to be locked, but use kern_path_locked() or kern_path_locked_negative() anyway. This is somewhat misleading to the casual reader. This patch introduces a more targeted function, kern_path_parent(), which returns not holding locks. On success the "path" will be set to the parent, which must be found, and the return value is the dentry of the target, which might be negative. This will clear the way to rename kern_path_locked() which is otherwise only used to prepare for removing something. It also allows us to remove kern_path_locked_negative(), which is transformed into the new kern_path_parent().

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.
