Subject: reduce sub-block DIO serialisation v3
Date: Thu, 21 Jan 2021 09:58:55 +0100 [thread overview]
Message-ID: <20210121085906.322712-1-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:
- add another sanity check in __iomap_dio_rw
- rename IOMAP_DIO_UNALIGNED to IOMAP_DIO_OVERWRITE_ONLY
- use more consistent parameter naming
- improve a few comments
- cleanup an if statement
Changes since v1:
- rename the new flags
- add an EOF check for subblock I/O
- minor cleanups
