Thanks for pointing that out!

I was going to ask this to Julia for the appropriate tag, but it slipped
my mind. In future I will definitely choose more appropriate tag
on the Coccinelle patches.

Just to give an insight of the problem to everyone :

While running checkpatch on patches involving the above Generated-by
tag, which is generally used to specify the cocci script used,
checkpatch prompts the below warning and error :

WARNING: Non-standard signature: Generated-by:
#10:
Generated-by: scripts/coccinelle/api/alloc/kzalloc-simple.cocci

ERROR: Unrecognized email address:
'scripts/coccinelle/api/alloc/kzalloc-simple.cocci'

Joe suggested to not use the "-by:" form since it should be reserved
for actual people's names and email addresses.
And if you use other tag than the "-by:" tag, then there is no
error/warning produced.

Thanks
