From 61551f1ee536289084a4a8f1c4f187e2f371c440 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 23 Aug 2011 08:28:06 +0000 Subject: xfs: call xfs_buf_delwri_queue directly Unify the ways we add buffers to the delwri queue by always calling xfs_buf_delwri_queue directly. The xfs_bdwrite functions is removed and opencoded in its callers, and the two places setting XBF_DELWRI while a buffer is locked and expecting xfs_buf_unlock to pick it up are converted to call xfs_buf_delwri_queue directly, too. Also replace the XFS_BUF_UNDELAYWRITE macro with direct calls to xfs_buf_delwri_dequeue to make the explicit queuing/dequeuing more obvious.
