<title>Applying Patches</title>
<para>
If you have a patch, or a small series of patches, to apply to the Linux kernel
If you have a single patch or a small series of patches
that you want to apply to the Linux kernel source, you
can do so just as you would with any other recipe.
You first copy the patches to the path added to
<ulink url='&YOCTO_DOCS_REF_URL;#var-FILESEXTRAPATHS'><filename>FILESEXTRAPATHS</filename></ulink>
in your <filename>.bbappend</filename> file as described in
the previous section, and then reference them in
<ulink url='&YOCTO_DOCS_REF_URL;#var-SRC_URI'><filename>SRC_URI</filename></ulink>
statements.
</para>
<para>
For example, you can apply a three-patch series by adding the
following lines to your linux-yocto <filename>.bbappend</filename>
file in your layer:
<literallayout class='monospaced'>
SRC_URI += "file://0001-first-change.patch"
SRC_URI += "file://0002-first-change.patch"
SRC_URI += "file://0003-first-change.patch"
</literallayout>
Then next time you run BitBake to build the Linux kernel, BitBake
detects the change in the recipe and fetches and applies the patches
before building the kernel.
