f2fs: do not trim preallocated blocks when truncating after i_size (2015-06-11 18:30:49 -0700)

----------------------------------------------------------------
New features are:
o per-file encryption (e.g., ext4)
o FALLOC_FL_ZERO_RANGE
o FALLOC_FL_COLLAPSE_RANGE
o RENAME_WHITEOUT

Major enhancement/fixes are to:
o recovery broken superblocks
o enhance f2fs_trim_fs with a discard_map
o fix a race condition on dentry block allocation
o fix a deadlock during summary operation
o fix a missing fiemap result

And many minor bug fixes and clean-ups were done.
