Subject: add RWF_(D)SYNC flag to preadv2/pwritev2 V2
Date: Thu, 7 Apr 2016 08:51:54 -0700 [thread overview]
Message-ID: <1460044324-5298-1-git-send-email-hch@lst.de> (raw)
Add per-I/O sync flags, which are very useful for all kinds of file servers
or storage targets. To properly do this refactor lots of direct I/O code
to not pass pointless argument, which makes the whole series a net negative
in terms of lines of code.
Changes since V1:
- fix RWF_SYNC defintion
- fix a comment
