From c37650161a53c01ddd88587675f9a4adc909a73e Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 6 Oct 2010 10:48:20 +0200 Subject: fs: add sync_inode_metadata Add a new helper to write out the inode using the writeback code, that is including the correct dirty bit and list manipulation. A few of filesystems already opencode this, and a lot of others should be using it instead of using write_inode_now which also writes out the data.
