NAME
       bitmap_parselist_user -

SYNOPSIS
       int bitmap_parselist_user(const char __user * ubuf, unsigned int ulen, unsigned long * maskp, int nmaskbits);

ARGUMENTS
       ubuf
	   pointer to user buffer containing string.

       ulen
	   buffer size in bytes. If string is smaller than this then it must be terminated with a .

       maskp
	   pointer to bitmap array that will contain result.

       nmaskbits
	   size of bitmap, in bits.

DESCRIPTION
       Wrapper for bitmap_parselist, providing it with user buffer.

       We cannot have this as an inline function in bitmap.h because it needs linux/uaccess.h to get the access_ok declaration and this causes
       cyclic dependencies.
