The NEED_* macros do an implicit goto in case the safety bounds checks fail. Add the unlikely hints as this is the error case and not a hot path. The final assembly is slightly shorter and some jumps got reordered according to the hints. text data bss dec hex filename 2294 16 0 2310 906 pre/lzo1x_decompress_safe.o 2277 16 0 2293 8f5 post/lzo1x_decompress_safe.o text data bss dec hex filename 3444 48 0 3492 da4 pre/lzo1x_compress_safe.o 3372 48 0 3420 d5c post/lzo1x_compress_safe.o Signed-off-by: David Sterba <dsterba@suse.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
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.
