Subject: reduce sub-block DIO serialisation v2
Date: Mon, 18 Jan 2021 20:35:05 +0100 [thread overview]
Message-ID: <20210118193516.2915706-1-hch@lst.de> (raw)
This takes the approach from Dave, but adds a new flag instead of abusing
the nowait one, and keeps a simpler calling convention for iomap_dio_rw.
Changes since v2:
- rename the new flags
- add an EOF check for subblock I/O
- minor cleanups
