bitmap_parse_user - convert an ASCII hex string in a user buffer into a bitmap
2. SYNOPSIS ▲
int bitmap_parse_user(const char __user * ubuf , unsigned int ulen , unsigned long * maskp , int nmaskbits );
3. ARGUMENTS ▲
pointer to user buffer containing string.
buffer size in bytes. If string is smaller than this then it must be terminated with a \0.
pointer to bitmap array that will contain result.
size of bitmap, in bits.
4. DESCRIPTION ▲
Wrapper for __bitmap_parse, 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.
