There are many "false" : "true" format in the kernel tree,
so we add str_false_true() as well.

Add str_true_false()/str_false_true() helper to "true" or "false"
string literal. And we found more than 10 cases currently exist
in the tree. So these helpers can be used for these cases.
Hongbo Li (2):
lib/string_choices: Add str_true_false() helper
lib/string_choices: Add wrapper for str_fa
Add str_true_false() helper to return "true" or "false"
string literal.

Introduce type-aware kmalloc-family helpers to replace the common
idioms for single, array, and flexible object allocations:
ptr = kmalloc(sizeof(*ptr), gfp);
ptr = kzalloc(sizeof(*ptr), gfp);
ptr = kmalloc_array(count, sizeof(*ptr), gfp);
ptr = kcalloc(count, sizeo
