sys/kern/kern_ksyms.c: revision 1.88 (patch)
When reading from /dev/ksyms we need to skip over entries that have
been marked as sd_gone. Otherwise we might try to uiomove() data from
memory that has been unmapped, resulting in EFAULT.
XXX This (along with other pre-existing checks st->sd_gone) is still
racy, but it's an improvement over current code. Ideally we would
make a complete copy of the symbol table when we open /dev/ksyms so
we could ignore any changes that occur.
ad@ says "good enough for now"
