[PATCH 0/3] remove shared memory structures

[Jaegeuk Kim]

This series removes the use of rb_entry based on memory alignment which doesn't
look like a right design when considering various architectures/compilers.

 v2 from v1:
  - adjusted Eric's review
  - refactored gc.c further to clean up

Jaegeuk Kim (3):
  f2fs: factor out victim_entry usage from general rb_tree use
  f2fs: factor out discard_cmd usage from general rb_tree use
  f2fs: remove entire rb_entry sharing
