+For all other submissions, choose one of the following procedures:

- - If the patch requires other patches as prerequisites which can be
- cherry-picked, then this can be specified in the following format in
- the sign-off area:
+
+ --- Option 2 ---
+
+ After the patch has been merged to Linus' tree, send an email to

+ it to be applied to.
+
+Option 1 is probably the easiest and most common. Options 2 and 3 are more
+useful if the patch isn't deemed worthy at the time it is applied to a public
+git tree (for instance, because it deserves more regression testing first).
+Option 3 is especially useful if the patch needs some special handling to apply
+to an older kernel (e.g., if API's have changed in the meantime).
+
+Additionally, some patches submitted via Option 1 may have additional patch
+prerequisites which can be cherry-picked. This can be specified in the following
