When truncating a file, file buffers which have already been allocated but not yet written may be truncated. Truncating these buffers could cause breakage of a sequential write pattern in a block group if the truncated blocks are for example followed by blocks allocated to another file. To avoid this problem, always wait for write out of all unwritten buffers before proceeding with the truncate execution. Signed-off-by: Naohiro Aota <naohiro.aota@xxxxxxx>
