From 22735068d53c7115e384bc88dea95b17e76a6839 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Mon, 18 Jul 2011 13:21:39 -0400 Subject: drivers: fix up various ->llseek() implementations Fix up a few ->llseek() implementations that won't deal with SEEK_HOLE/SEEK_DATA properly. Make them future proof so that if we ever add new options they will return -EINVAL.
