Hello Hans,

Filesystems don't usually wait on the IO to complete before submitting
more IO in response to the next write() syscall.  They can do this by
batching a whole bunch of operations into one committed transaction.

     

Is there a timeout mechanism for batching operations.

At some point due to its age or size you decide the batch needs to commit.

What if certain 
operation
is done after the batch operation is executed. Does it mean that the new 
operation has to wait.
   

You don't have to wait unless you run out of available non-dirty memory, or
issue a call to sync to the disks.
