From f2bde9b89b4d67c9bc3b963cb996f449ddcd27a4 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 24 Jun 2010 11:44:35 +1000 Subject: [PATCH] xfs: small cleanups for xfs_iomap / __xfs_get_blocks Remove the flags argument to __xfs_get_blocks as we can easily derive it from the direct argument, and remove the unused BMAPI_MMAP flag.
