From bd5a876ac4c130e8e1986dcdbb21839ae4cd91c0 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 21 Jun 2005 15:47:39 +1000 Subject: [XFS] (mostly) remove xfs_inval_cached_pages Since the last round of direct I/O locking changes it is just a wrapper around VOP_FLUSHINVAL_PAGES, so it's not nessecary anymore. Keep a simplified version for kernels < 2.4.22, as these don't have the changed direct I/O locking.
