f2fs: readahead encrypted block during GC (2018-08-20 23:13:42 -0700)

----------------------------------------------------------------
f2fs-for-4.19-rc1

In this round, we've tuned f2fs to improve general performance by serializing
block allocation and enhancing discard flows like fstrim which avoids user IO
contention. And we've added fsync_mode=nobarrier which gives an option to user
where it skips issuing cache_flush commands to underlying flash storage. And
there are many bug fixes related to fuzzed images, revoked atomic writes, quota
ops, and minor direct IO.

Enhancement:
- add fsync_mode=nobarrier which bypasses cache_flush command
- enhance the discarding flow which avoids user IOs and issues in LBA order
- readahead some encrypted blocks during GC
- enable in-memory inode checksum to verify the blocks if F2FS_CHECK_FS is set
- enhance nat_bits behavior
- set -o discard by default
- set REQ_RAHEAD to bio in ->readpages

Bug fixes:
- fix a corner case to corrupt atomic_writes revoking flow
- revisit i_gc_rwsem to fix race conditions
- fix some dio behaviors captured by xfstests
- correct handling errors given by quota-related failures
- add many sanity check flows to avoid fuzz test failures
- add more error number propagation to their callers
- fix several corner cases to continue fault injection w/ shutdown loop
