This is indeed another solution. But Joao was trying to use the
BR2_GLOBAL_PATCH_DIR mechanism, which allows to provide custom patches
for *any* package, and not only specifically for the Linux kernel.
Essentially, the "Custom kernel patches" mechanism you points to
predates the BR2_GLOBAL_PATCH_DIR mechanism. We keep it for
compatibility reasons, but generally consider BR2_GLOBAL_PATCH_DIR to
be the "better way".
Best regards,
Thomas
