From 4bc1ea6b8ddd4f2bd78944fbe5a1042ac14b1f5f Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Mon, 12 Nov 2012 22:53:56 +1100 Subject: [PATCH] xfs: remove xfs_flush_pages It is a complex wrapper around VFS functions, but there are VFS functions that provide exactly the same functionality. Call the VFS functions directly and remove the unnecessary indirection and complexity. We don't need to care about clearing the XFS_ITRUNCATED flag, as that is done during .writepages. Hence is cleared by the VFS writeback path if there is anything to write back during the flush.
