Subject: [linux-directio] DIO 512 KB limitation
Message-ID: <1084489592.25488.196435079@webmail.messagingengine.com>

Hi,

I had a Q reg. Linux's 512 KB DIO limitation. I dont understand the 512
KB limitation that exists. I see that every every kiobuf has 1024 buffer
heads allocated during alloc_kiovec. That means we should be able to
transfer (1024 * blocksize) number of bytes. So why is KIO_MAX_ATOMIC_IO
512 KB?

Thanks,
 
Tridib
