Re: [PATCH] sysctl: Check length at deprecated_sysctl_warning.

Hello.

Thanks for reformatting my patch
and sorry for surprising you with directory name
(I meant to type linux-2.6.24-rc2, not linux-2.6.22-rc2).

According to linux-2.6.23,
it seems that I should return -ENOTDIR
for invalid args->nlen value.

I got a question here regarding interpretation of CTL_MAXNAME .
Is args->nlen == CTL_MAXNAME valid?
It is treated as invalid while the definition says

/* how many path components do we allow in a
call to sysctl? In other words, what is
the largest acceptable value for the nlen
member of a struct __sysctl_args to have? */

If "name[CTL_MAXNAME];" is what the author intended,
I think args->nlen == CTL_MAXNAME is valid.

Regards.
