In Linux commit 560e20e4bf6484a0c12f9f3c7a1aa55056948e1e, the fsync_bdev() function was removed in favor of sync_blockdev() to do (roughly) the same thing, given the same input. This change conditionally attempts to call sync_blockdev() if fsync_bdev() isn't discovered during configure. Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Coleman Kane <ckane@colemankane.org> Closes #15263
