I got OOM killers while running heavy disk I/O (extracting kernel source, running lxr's genxref command). (Environ: 4 CPUs / 2048MB RAM / no swap / XFS) Do you think these OOM killers reasonable? Too weak against fragmentation? [ 3902.430630] kthreadd invoked oom-killer: order=2, oom_score_adj=0,

[PATCH V5 9/9] hvsock: introduce Hyper-V VM Sockets feature

Hyper-V VM sockets (hvsock) supplies a byte-stream based communication mechanism between the host and a guest. It's kind of TCP over VMBus, but the transportation layer (VMBus) is much simpler than IP. With Hyper-V VM Sockets, applications between the host and a guest can talk with each other

[PATCH V5 6/9] Drivers: hv: vmbus: add a hvsock flag in struct hv_driver

Only the coming hv_sock driver has a "true" value for this flag. We treat the hvsock offers/channels as special VMBus devices. Since the hv_sock driver handles all the hvsock offers/channels, we need to tweak vmbus_match() for hv_sock driver, so we introduce this flag. Signed-off-by: Dexuan Cui

[PATCH V5 3/9] Drivers: hv: vmbus: define a new VMBus message type for hvsock

A function to send the type of message is also added. The coming net/hvsock driver will use this function to proactively request the host to offer a VMBus channel for a new hvsock connection. Signed-off-by: Dexuan Cui --- drivers/hv/channel.c | 15 +++

pxa2xx-uart was a separate uart platform driver. It was declaring the same device names and numbers as 8250 driver. As a result, it was impossible to use 8250 driver on PXA SoCs. Upon closer examination pxa2xx-uart turned out to be a clone of 8250_core driver. Workaround for Erratum #19
