[PATCH v3 12/16] treewide: Use array_size() for kmalloc()-family
From: Kees Cook
Date: Thu May 31 2018 - 20:44:56 EST
For kmalloc()-family allocations, instead of A * B, use array_size().
Similarly, instead of A * B *C, use array3_size().
Note that:
kmalloc(array_size(a, b), ...);
could be written as:
kmalloc_array(a, b, ...)
(and similarly, kzalloc(array_size(a, b), ...) as kcalloc(a, b, ...))
but this made the Coccinelle script WAY larger. There is no desire to
replace kmalloc_array() with kmalloc(array_size(...), ...), but given
the number of changes made treewide, I opted for Coccinelle simplicity.
This also tries to isolate sizeof() and constant factors, in an attempt
to regularize the argument ordering.
Automatically generated using the following Coccinelle script:
