From a206c817c864583c44e2f418db8e6c7a000fbc38 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 10 Dec 2010 08:42:20 +0000 Subject: xfs: kill xfs_iomap Opencode the xfs_iomap code in it's two callers. The overlap of passed flags already was minimal and will be further reduced in the next patch. As a side effect the BMAPI_* flags for xfs_bmapi and the IO_* flags for I/O end processing are merged into a single set of flags, which should be a bit more descriptive of the operation we perform. Also improve the tracing by giving each caller it's own type set of tracepoints.
