From 1e5e59d431038c53954fe8f0b38bee0f0ad30349 Mon Sep 17 00:00:00 2001 From: Jeff Mahoney Date: Mon, 30 Mar 2009 14:02:27 -0400 Subject: [PATCH] reiserfs: introduce reiserfs_error() Although reiserfs can currently handle severe errors such as journal failure, it cannot handle less severe errors like metadata i/o failure. The following patch adds a reiserfs_error() function akin to the one in ext3. Subsequent patches will use this new error handler to handle errors more gracefully in general.
