Why can't splice use MSG_MORE for the individual pages?
Why does tcp_sendpage need to know if the MORE indicator is coming from the
user or from splice?
I also don't understand your comment about partial writes.

To avoid possible ECC/parity checksum errors when reading an
uninitialized buffer, the entire Message RAM is initialized when probing
the driver. This initialization is done in the same function reading the
Device Tree properties.
This patch moves the RAM initialization to a separate function so i
This adds Power Management deep Suspend/Resume support for Bosch M_CAN
chip.
When entering deep sleep, the clocks are gated, the interrupts are
disabled. When resuming from deep sleep, the chip needs to be
reinitialized, the clocks ungated and the interrupts enabled.

Packet size is 64bytes.

Hello,
I have recently had occasion to use SOCK_SEQPACKET sockets on Linux,
and noticed some odd behavior. When using sendmsg and recvmsg with
these sockets, it seems that the "end-of-record" flag (MSG_EOR) is not
being propagated correctly.
It depends wh

I see no advantage in this, why? All it does is make the code longer,
and if anything changes, you have to change it in multiple places now.
