From 152a7b0a808a00601328feba2001cbb2b530f771 Mon Sep 17 00:00:00 2001 From: Tao Ma Date: Sun, 2 Dec 2012 11:13:24 -0500 Subject: [PATCH] ext4: move extra inode read to a new function Currently, in ext4_iget we do a simple check to see whether there does exist some information starting from the end of i_extra_size. With inline data added, this procedure is more complicated. So move it to a new function named ext4_iget_extra_inode.
