From 65d3000520c50f3c160403a210a7504d789eafca Mon Sep 17 00:00:00 2001 From: Tahsin Erdogan Date: Wed, 21 Jun 2017 22:24:38 -0400 Subject: [PATCH] ext4: ext4_xattr_delete_inode() should return accurate errors In a few places the function returns without trying to pass the actual error code to the caller. Fix those.
