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.
