lib/bitmap.c and corresponding include/linux/bitmap.h are intended to hold functions related to operations on bitmaps, like bitmap_shift or bitmap_set. Historically, some string-related operations like bitmap_parse are also reside in lib/bitmap.c. Now that the subsystem evolves, string-related bitmap operations became a significant part of the file. Because they are quite different from the other bitmap functions by nature, it's worth to split them to a separate source/header files.
