[GIT PULL] f2fs: request for tree inclusion

[Jaegeuk Kim]

Hi Linus,

This is the first pull request for tree inclusion of Flash-Friendly File
System (F2FS) towards the 3.8 merge window.

http://en.wikipedia.org/wiki/F2FS

The f2fs has been in the linux-next tree for a while, and several issues
have been cleared as described in the signed tag below.
And also, I've done testing f2fs successfully based on Linux 3.7 with
the following test scenarios.

- Reliability test:
  Run fsstress on an SSD partition.

- Robustness test:
  Conduct sudden-power-off and examine the fs consistency repeatedly,
  while running a reliability test.

So, please pull the f2fs filesystem.
If I'm missing any issues or made mistakes, please let me know.

Thanks,
Jaegeuk Kim
