xfs: don't allocate an ioend for direct I/O completions
Back in the days when the direct I/O ->end_io callback could be called from interrupt context for AIO we needed a structure to hand off to the workqueue, and reused the ioend structure for this purpose. These days ->end_io is always called from user or workqueue context, which allows us to avoid this memory allocation and simplify the code significantly. [dchinner: removed now unused xfs_finish_ioend_sync() function after Brian Foster did an initial review. ] Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com>
