Converting binder_debug() and binder_user_error() macros into functions
reduces the overall object size by 16936 bytes when cross-compiled with
aarch64-linux-gnu-gcc 11.2.0:
$ size drivers/android/binder.o.{old,new}
text data bss dec hex filename
77935 6168 20264 104367 197af drivers/android/binder.o.old
65551 1616 20264 87431 15587 drivers/android/binder.o.new
This is particularly beneficial to functions binder_transaction() and
binder_thread_write() which repeatedly use these macros and are both
part of the critical path for all binder transactions.
$ nm --size vmlinux.{old,new} |grep ' binder_transaction$'
0000000000002f60 t binder_transaction
0000000000002358 t binder_transaction
$ nm --size vmlinux.{old,new} |grep binder_thread_write
0000000000001c54 t binder_thread_write
00000000000014a8 t binder_thread_write

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.
