From f4e6b498d6e06742d72706ef50593a9c4dd72214 Mon Sep 17 00:00:00 2001 From: Fengguang Wu Date: Tue, 16 Oct 2007 01:24:33 -0700 Subject: readahead: combine file_ra_state.prev_index/prev_offset into prev_pos Combine the file_ra_state members unsigned long prev_index unsigned int prev_offset into loff_t prev_pos It is more consistent and better supports huge files. Thanks to Peter for the nice proposal!
