The underlying problem is of course that all those sanity checks should be done in user space, not in the kernel. (See also ftp://icaftp.epfl.ch/pub/people/almesber/slides/tmp-tc.ps.gz The bitching starts on slide 11, some ideas for fixing the problem on slide 16, but heed the warning on slide 15.) Besides that, I agree that we have far too many EINVALs in the kernel. Maybe we should just record file name and line number of the EINVAL in *current and add an eh?(2) system call ;-) - Werner -- _________________________________________________________________________ / Werner Almesberger, ICA, EPFL, CH [EMAIL PROTECTED] / /_IN_N_032__Tel_+41_21_693_6621__Fax_+41_21_693_6610_____________________/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
