From dc1841d6cff22b98deef46bfe768a9c678d917c2 Mon Sep 17 00:00:00 2001 From: Lukas Czerner Date: Mon, 19 Mar 2012 23:07:43 -0400 Subject: [PATCH] ext4: give more helpful error message in ext4_ext_rm_leaf() The error message produced by the ext4_ext_rm_leaf() when we are removing blocks which accidentally ends up inside the existing extent, is not very helpful, because we would like to also know which extent did we collide with. This commit changes the error message to get us also the information about the extent we are colliding with.
