[Feature request]: add option to dd to fsync|fdatasync after each block written
Suppose I want to show progress with: pv image.img | dd bs=16M of=/dev/sdc it will not work, as dd will write to sdc momentarily. dd will hang on close(1) waiting for actual write to complete (tested on USB stick Linux 2.6.32) I decide to use oflag=direct. It help, OK. But: http://kerneltrap.org/node/7563 It will be nice if, dd will be able to fsync/fdatasync after each block. I think, it is useful for other usages. -- Segmentation fault
