When CONFIG_CC_OPTIMIZE_FOR_DEBUGGING is enabled, the compiler fails to optimize out a dead code path, which leads to a link failure: net/openvswitch/conntrack.o: In function `ovs_ct_set_labels': conntrack.c:(.text+0x2e60): undefined reference to `nf_connlabels_replace' In this configuration, we can take a shortcut, and completely remove the contrack label code. This may also help the regular optimization. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: David S. Miller <davem@davemloft.net>
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.
