kvasprintf

函数名称：If fmt contains no % (or is exactly %s), use kstrdup_const. If fmt* (or the sole vararg) points to rodata, we will then save a memory* allocation and string copy. In any case, the return value should be* freed using kfree_const().

函数原型：const char *kvasprintf_const(gfp_t gfp, const char *fmt, va_list ap)

返回类型：char

参数：

类型	参数	名称
gfp_t	gfp
const char *	fmt
va_list	ap

如果非strchr(fmt, '%')则返回:kstrdup_const - conditionally duplicate an existing const string*@s: the string to duplicate*@gfp: the GFP mask used in the kmalloc() call when allocating memory* Note: Strings allocated by kstrdup_const should be freed by kfree_const.

如果非strcmp(fmt, "%s")则返回:kstrdup_const - conditionally duplicate an existing const string*@s: the string to duplicate*@gfp: the GFP mask used in the kmalloc() call when allocating memory* Note: Strings allocated by kstrdup_const should be freed by kfree_const.

返回:Simplified asprintf.
