Expose in /sys/fs/f2fs//main_blkaddr the block address where the
main area starts. This allows user mode programs to determine:
- That pinned files that are made exclusively of fully allocated 2MB
segments will never be unpinned by the file system.
- Where the main area starts. This is
We must stop GC, once the segment becomes fully valid. Otherwise, it can
produce another dirty segments by moving valid blocks in the segment partially.
Ramon hit no free segment panic sometimes and saw this case happens when

Implemented cache options in F2FS configuration 'c' (i.e. user
options):
* use c.cache_config.num_cache_entry to set the number of
cache entries (in block), minimum 1024, or 0 to disable cache.
* use c.cache_config.max_hash_collision to set maximum hash

Fix file system corruption when using LFS mount (e.g., in zoned
devices). Seems like the fallback into buffered I/O creates an
inconsistency if the application is assuming both read and write DIO. I
can easily reproduce a corruption with a simple RocksDB test.
