Hello all,
(and some specific gurus in particular...)
Having set the frandom kernel module free
(http://www.billauer.co.il/frandom.html) , it turns out that people have
had trouble compiling it (which strangely enough, indicates that some
people may have actually found it useful ;).
It seems like the kdev_t_to_nr macro has disappeared from the kernel
somewhere between 2.6.0 and now. There are also indications that saying
#define kdev_t_to_nr(x) (x)
is a good idea. Can anyone shed some light on this? Do I need to update
my module?
For those interested, typical use of the macro for checking which minor
the inode was opened with:
static int frandom_open(struct inode *inode, struct file *filp)
{
struct frandom_state *state;
int num =MINOR(kdev_t_to_nr(inode->i_rdev));
if ((num != frandom_minor) && (num != erandom_minor)) return -ENODEV;
(...etc...)
}
Thanks,
Eli
