Name
bitmap_parselist_user —
Synopsis
int bitmap_parselist_user ( | const char __user * ubuf, |
| | unsigned int ulen, |
| | unsigned long * maskp, |
| | int nmaskbits); |
Arguments
const char __user * ubuf
pointer to user buffer containing string.
unsigned int ulen
buffer size in bytes. If string is smaller than this
then it must be terminated with a \0.
unsigned long * maskp
pointer to bitmap array that will contain result.
int 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.
