lib/vsprintf.c

lib/vsprintf.c exports (using EXPORT_SYMBOL, see include/linux/export.h) the following functions:

• simple_strtoull
• simple_strtoul
• simple_strtol
• simple_strtoll
• vsnprintf
• vscnprintf
• snprintf
• scnprintf
• vsprintf
• sprintf
• vsscanf
• sscanf

The four simple_X functions explicitly ignore overflows. A more correct replacement (which unlike simple_X requires a NUL-terminated string are kstrtol, kstrtoll, kstrtoul and kstrtoull.
