From 34ce4e7c23e3da578e459b05c6fb17edecb19e6b Mon Sep 17 00:00:00 2001 From: Boaz Harrosh Date: Tue, 15 Dec 2009 19:34:17 +0200 Subject: exofs: debug print even less * Last debug trimming left in some stupid print, remove them. Fixup some other prints * Shift printing from inode.c to ios.c * Add couple of prints when memory allocation fails.
