This series introduces a new generic function strtolower(), which converts strings to lowercase in-place, overwriting the original string. This kind of functionality is needed in several places in the kernel. Right now, everybody seems to be implementing their own copy of this function. So, we replace several custom "strtolower" implementations with this new library function. Another

This series introduces a family of generic string case conversion functions. This kind of functionality is needed in several places in the kernel. Right now, everybody seems to be implementing their own copy of this functionality. Based on the discussion of the previous version of this series[1] and the use cases found in the kernel, it does look like having several flavours of case conversion
