ocfs2: Add extended attribute support
This patch implements storing extended attributes both in inode or a single external block. We only store EA's in-inode when blocksize > 512 or that inode block has free space for it. When an EA's value is larger than 80 bytes, we will store the value via b-tree outside inode or block. Signed-off-by: Tiger Yang <tiger.yang@oracle.com> Signed-off-by: Mark Fasheh <mfasheh@suse.com>
