Subject: reiserfs: Initialize inode keys properly
From: Jan Kara <jack@xxxxxxx>
commit 4443390e08d34d5771ab444f601cf71b3c9634a4 upstream.
reiserfs_read_locked_inode() didn't initialize key length properly. Use
_make_cpu_key() macro for key initialization so that all key member are
properly initialized.
