f2fs: hurry up to issue discard after io interruption (2017-09-12 10:02:55 -0700)


In this round, we've mostly tuned f2fs to provide better user experience
for Android. Especially, we've worked on atomic write feature again with
SQLite community in order to support it officially. And we added or modified
several facilities to analyze and enhance IO behaviors.

Major changes include:
- add app/fs io stat
- add inode checksum feature
- support project/journalled quota
- enhance atomic write with new ioctl() which exposes feature set
- enhance background gc/discard/fstrim flows with new gc_urgent mode
- fix some quota flows
