From e1c54b64027b52ba43b86fe6219910a9e9a88b73 Mon Sep 17 00:00:00 2001 From: Jan Blunck Date: Wed, 26 May 2010 14:44:44 -0700 Subject: [PATCH] osst: update ppos instead of using file->f_pos osst_read()/osst_write() modify file->f_pos directly instead of the ppos given to them. The VFS later updates the file->f_pos and overwrites it with the value of ppos.
