Subject: [GIT PULL] iomap: small cleanups for 5.5

Hi Linus,

Please pull this series containing some more new iomap code for 5.5.
There's not much this time -- just removing some local variables that
don't need to exist in the iomap directio code.

The branch merges cleanly against this morning's HEAD and survived a few
days' worth of xfstests.  The merge was completely straightforward, so
please let me know if you run into anything weird(er than my dorky tag


The following changes since commit 419e9c38aa075ed0cd3c13d47e15954b686bcdb6:

  iomap: Fix pipe page leakage during splicing (2019-11-22 08:36:02 -0800)

  iomap: remove unneeded variable in iomap_dio_rw() (2019-11-26 09:28:47 -0800)

New code for 5.5:
- Make iomap_dio_rw callers explicitly tell us if they want us to wait
- Port the xfs writeback code to iomap to complete the buffered io
  library functions
- Refactor the unshare code to share common pieces
- Add support for performing copy on write with buffered writes
- Other minor fixes
- Fix unchecked return in iomap_bmap
- Fix a type casting bug in a ternary statement in iomap_dio_bio_actor
- Improve tracepoints for easier diagnostic ability
- Fix pipe page leakage in directio reads
- Clean up iter usage in directio paths
