Coverity complains about the lack of error checking in the following
code in sys/kern/kern_sysctl.c, around line 1390:
/*
* Touch all the wired pages to avoid PTE modified
* bit emulation traps on Alpha while holding locks
* in the sysctl handler.
*/
for (i = (wiredlen + PAGE_SIZE - 1) / PAGE_SIZE,
cp = req->oldptr; i > 0; i--, cp += PAGE_SIZE) {
copyin(cp, &dummy, 1);
copyout(&dummy, cp, 1);
}
Since Alpha is dead, can we remove this, or is it still needed for other
platforms?
