14 A frequently asked question on the Linux Kernel Mailing List is how to apply
19 In addition to explaining how to apply and revert patches, a brief
20 description of the different kernel trees (and examples of how to apply
31 To correctly apply a patch you need to know what base it was generated from
37 How do I apply or revert a patch?
40 You apply a patch with the ``patch`` program. The patch program reads a diff
122 options. It can either refuse to apply the changes and abort or it can try
123 to find a way to make the patch apply with a few minor changes.
131 usually adjust the line numbers and apply the patch.
145 only patches from kernel.org and you apply the patches in the correct order,
170 This often happens if you try to apply a patch that was generated against a
183 If you actually did apply this patch previously and you just re-applied it
190 the patch will in fact apply it.
201 As I already mentioned above, these errors should never happen if you apply
206 wish to apply.
217 apply the result.
277 To apply a patch moving from 5.6 to 5.7, you'd do the following (note
278 that such patches do **NOT** apply on top of 5.x.y kernels but on top of the
287 	$ patch -p1 < ../patch-5.7	# apply the 5.7 patch
296 	$ patch -p1 < ../patch-5.7	# apply new 5.7 patch
316 how to apply these patches.
322 patch does not apply on top of the 5.7.2 kernel source, but rather on top
325 So, in order to apply the 5.7.3 patch to your existing 5.7.2 kernel
327 base 5.7 kernel source) and then apply the new 5.7.3 patch.
333 	$ patch -p1 < ../patch-5.7.3	# apply the new 5.7.3 patch
344 Here's the example to apply these::
347 	$ patch -p1 < ../patch-5.7.2-3	# apply the new 5.7.3 patch
369 The -rc patches are not incremental, they apply to a base 5.x kernel, just
377 Here are 3 examples of how to apply these patches::
382 	$ patch -p1 < ../patch-5.8-rc3		# apply the 5.8-rc3 patch
390 	$ patch -p1 < ../patch-5.8-rc5		# apply the new 5.8-rc5 patch
398 	$ patch -p1 < ../patch-5.8-rc5		# apply new 5.8-rc5 patch
