Currently, it only works in readonly format f2fs image.

There wouldn't be any race condition because unaligned extent only works
for ro feature now?

Isn't your patch proposing on writable partition?

Please check description in patch message, now it was designed only for
compression case w/ ro feature, let's check and support rw partition later.


Is there any race condition between the address in extent_cache and the one in
dnode? I feel that we could synchronize it by locking its dnode block.
