  Hello,

  this patch set fixes two races between truncate and writeback code.
The first one was introduced by my rewrite of ext4 writeback path and
Dave and Zheng have spotted them in their testing. It could result in
some leaked fs blocks and delalloc accounting mismatch. The first two
patches fix that bug.

The second race has been there for ages and could result in i_size being
wrong on disk. The last two patches fix that race.
