[cocci] [PATCH v1 0/1] scripts/coccinelle: Add script for using ARRAY_END()

[Alejandro Colomar <alx@kernel.org>]

Hi!

This is a script to help find and replace uses of ARRAY_SIZE() to find
the end of an array (a pointer one past the last element).  We already
replaced some uses a few months ago, fixing some bugs while doing that,
and now I've written a coccinelle patch to do it elsewhere.

This is the first time I write a script under scripts/coccinelle/, so
take it with a grain of salt.  I've tested it, and I see no false
positives.  However, I've found several false negatives (for example,
in macros, or where the argument is a struct member).


Have a lovely night!
Alex
