revision 1.66
date: 2007/07/31 06:23:26; author: marcel; state: Exp; lines: +2 -2
Fix backward compatibility of the "old" (i.e. FreeBSD6) lseek
syscall. It was broken when a new lseek syscall was introduced.
The problem is that we need to swap the 32-bit td_retval values
for the __syscall indirect syscall when the actual syscall has
a 32-bit return value. Hence, we need to exclude lseek(2). And
this means the "old" lseek(2) as well -- which we didn't.
Based on a patch from: grehan@
Approved by: re (blanket)
