f2fs: upset segment_info repair (2015-09-01 14:45:27 -0700)
----------------------------------------------------------------
The major work includes fixing and enhancing the existing extent_cache feature,
which has been well settling down so far and now it becomes a default mount
option accordingly.
Also, this version newly registers a f2fs memory shrinker to reclaim several
objects consumed by a couple of data structures in order to avoid memory
pressures.
Another new feature is to add ioctl(F2FS_GARBAGE_COLLECT) which triggers a
cleaning job explicitly by users.
Most of the other patches are to fix bugs occurred in the corner cases across
the whole code area.
