From a14a5ab58f9d783ec3a2a287320fab22e1764813 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 18 Feb 2010 12:43:22 +0000 Subject: xfs: remove xfs_ipin/xfs_iunpin Inodes are only pinned/unpinned via the inode item methods, and lots of code relies on that fact. So remove the separate xfs_ipin/xfs_iunpin helpers and merge them into their only callers. This also fixes up various duplicate and/or incorrect comments.
