  f2fs: fix to skip shrinking extent nodes (2015-10-22 09:39:35 -0700)

----------------------------------------------------------------
Most part of the patches include enhancing the stability and performance of
in-memory extent caches feature.

In addition, it introduces several new features and configurable points:
 - F2FS_GOING_DOWN_METAFLUSH ioctl to test power failures
 - F2FS_IOC_WRITE_CHECKPOINT ioctl to trigger checkpoint by users
 - background_gc=sync mount option to do gc synchronously
 - periodic checkpoints
 - sysfs entry to control readahead blocks for free nids

And the following bug fixes have been merged.
- fix SSA corruption by collapse/insert_range
- correct a couple of gc behaviors
- fix the results of f2fs_map_blocks
- fix error case handling of volatile/atomic writes

----------------------------------------------------------------
