SequentialWriter doesn't fsync() before posix_fadvise()
-------------------------------------------------------
Key: CASSANDRA-3948
URL: https://issues.apache.org/jira/browse/CASSANDRA-3948
Project: Cassandra
Issue Type: Bug
Reporter: Peter Schuller
This should make the fadvising useless (mostly). See CASSANDRA-1470 for why,
including links to kernel source. I have not investigated the history of when
this broke or whether it was like from the beginning.
For the record I have not confirmed this by testing, only by code inspection. I
happened to notice it working on other things, so there is some chance that I'm
just mis-reading the code.
