SVN rev 193438 on 2009-06-04 15:10:29Z by kib
MFC r192094:
Do not advance req->oldidx when sysctl_old_user returning an
error due to copyout failure or short buffer.
MFC r192144:
Revert r192094. The revision caused problems for sysctl(3) consumers
that expect that oldlen is filled with required buffer length even when
supplied buffer is too short and returned error is ENOMEM.
Redo the fix for kern.proc.filedesc, by reverting the req->oldidx when
remaining buffer space is too short for the current kinfo_file structure.
Also, only ignore ENOMEM. We have to convert ENOMEM to no error condition
to keep existing interface for the sysctl, though.
