The lockdep_is_held() macro is defined as: #define lockdep_is_held(lock) lock_is_held(&(lock)->dep_map) This hides away the dereference, so that builds with !LOCKDEP don't break. This works in current kernels because the RCU_LOCKDEP_WARN() eliminates its condition at preprocessor time in !LOCKDEP kernels. However, later patches in this series will cause the compiler to see this condition even in !LOCKDEP kernels. This commit prepares for this upcoming change by switching from lock_is_held() to lockdep_is_held().

README
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.
