From 180bfb31fef77815d56b875d4f28d353fdc87bf8 Mon Sep 17 00:00:00 2001 From: Vitaly Wool Date: Tue, 6 Mar 2007 17:01:04 +0300 Subject: [PATCH] [JFFS2] Fix writebuffer recovery in the first page of a block For the case when nand_write_page fail with -EIO for the first page in an eraseblock, jffs2_wbuf_recover ends up producing a BUG in jffs2_block_refile as jeb->first_node is not yet set up (it's set up later in jffs2_wbuf_recover). This BUG is not really a bug; it's just jffs2_wbuf_recover calling jffs2_block_refile with the wrong second parameter. This patch takes care of this situation.
