From b361acb1083f0b313a4b398de48450f5edb81fe1 Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Sun, 27 Apr 2008 15:38:26 +0200 Subject: [PATCH] ide-tape: remove idetape_pipeline_size() The computation of the block offset of the the tape position (MTIOCPOS, MTIOCGET) is not influenced by the stages queued in the pipeline anymore but by the size of the current buffer which is going to be sent to the drive.
