Man page 9 : bitmap_parselist_user

bitmap_parselist_user -

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

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 \0.

maskp
    pointer to bitmap array that will contain result.

nmaskbits
    size of bitmap, in bits.

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.
