Leaving stat() to report PAGE_SIZE as the block size causes test programs like fsx to issue illegal ranges for operations that require block size alignment (e.g. fallocate() insert range). Hence update the preferred IO size to reflect the block size in this case. This change is based on a patch originally from Dave Chinner.[1] [1] https://lwn.net/ml/linux-fsdevel/20181107063127.3902-16-david@fromorbit.com/ Signed-off-by: Pankaj Raghav Signed-off-by: Luis Chamberlain Reviewed-by: Darrick J.
