I have taken another look at this script for the semantic patch language.
I imagined that I could refactor the shown SmPL disjunctions a bit.
But I noticed then that these SmPL rules contain a development mistake.
The deletion for a call of the function “memset” depends on the specification
that a size determination is passed by the expression “E1”.
The function “kmem_cache_alloc” was specified despite of the technical detail
that this function does not get a parameter passed which would correspond
to such a size information.

https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/tree/tools/testing/radix-tree/linux/slab.h?idS7659c08a7da298aa748854f65f2aa1f31b1378#n14
Thus I suggest to remove it from the first two SmPL rules and omit the rule “r4”.
Will the rule set be more consistent then?
Regards,
Markus
