This patch series cleans up and rewrites parts of the code used to free
clusters or blocks when space is removed from a file.  The intent is to
improve the readability, clarity, and efficiency of that code.  These
changes do not fix any known bugs.

Eric Whitney (6):
  ext4: consolidate code used to free clusters
  ext4: rework partial cluster definition and related tracepoints
  ext4: rework partial cluster handling to use lblk more consistently
  ext4: consolidate partial cluster initialization
  ext4: simplify and improve efficiency of cluster removal code
  ext4: remove mballoc's NOFREE flags
