From 9a1fcdfd4bee27c418424cac47abf7c049541297 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Mon, 29 May 2006 14:56:39 +0200 Subject: [MTD] NAND Signal that a bitflip was corrected by ECC Return -EUCLEAN on read when a bitflip was detected and corrected, so the clients can react and eventually copy the affected block to a spare one. Make all in kernel users aware of the change.
