Allow block device to be configured in the buffered I/O mode by using the file backend. In this way now we can use cache for the block device namespace which shows significant performance improvement. We update the block device ns enable function and return early when buffered_io flag is set. Signed-off-by: Chaitanya Kulkarni <kch@nvidia.com> Signed-off-by: Christoph Hellwig <hch@lst.de> |
