Re: [PATCH 3/5] af_vsock: send/receive loops for SOCK_SEQPACKET.

Hmm, are you sure you need to convert
"err" to the pointer, just to return true/false
as the return value?
How about still returning "err" itself?

In this case i need to reserve some value for
"err" as success, because both 0 and negative
values are passed to caller when this function
returns false(check failed). May be i will
inline this function.

Its not very clear (only for me perhaps) how
dequeue_total and len correlate. Are they
equal here? Would you need to check that
dequeued_total >= record_len?
I mean, its just a bit strange that you check
dequeued_total>0 and no longer use that var
inside the block.

When "dequeued_total > 0" record copy is succeed.
"len" is length of user  buffer. I think i can
replace "dequeued_total" to some flag, like "error",
because in SOCK_SEQPACKET mode record could be
copied whole or error returned.
