Hi!

i'm interested in zil's behavior.

it's my understanding that zil is used only when
synchronous(o_sync,o_dsync & directio) write io request.
then zil have written contents that system call is used by zil replay
when used by crashed.
is this correct?
It seems a large amount of io for system call.
I think maybe the real data is being written in zil.

Thanks a lot!
