Git Reversing patches

You can reverse a patch if you have finished testing it, or if you want to see whether a problem has been introduced by a particular patch.

You should also reverse a patch prior to adding a newer, updated version of the same patch.

To reverse the patch, use the patch command with the -R option:

patch -p1 -R < path/file.patch

(If your patch was applied with the -p0 option, use that instead.)

Or:

git apply -R path/file.patch
