From a8d770d987ee20b59fba6c37d7f0f2a351913c4b Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Mon, 6 Apr 2009 18:44:54 +0200 Subject: xfs: use xfs_sync_inodes() for device flushing Currently xfs_device_flush calls sync_blockdev() which is a no-op for XFS as all it's metadata is held in a different address to the one sync_blockdev() works on. Call xfs_sync_inodes() instead to flush all the delayed allocation blocks out. To do this as efficiently as possible, do it via two passes - one to do an async flush of all the dirty blocks and a second to wait for all the IO to complete. This requires some modification to the xfs-sync_inodes_ag() flush code to do efficiently.
