Re: Which version will be merged into mainline kernel?

[Christopher Chan]

So the bad case is:
1. mails are tiny
2. RAM cache is big
3. cache doesn't get flushed to disk for 1000s of mails
4. crash happens seldomly, but severely :)
-> 1000s of mail lost by the crash
Now I see :)

:). So fsync/fsyncdata takes care of those rare crashes which is why 
mail servers should rarely lose mail. I say should because the journal 
mode available/used affects fsync/fsyncdata too.
