Hi Peter,
I find one list API usage may not be correct in current fair.c code.
In move_one_task function, it may iterate through whole cfs_tasks
list to get one task to move.
But in dequeue_task(), it would delete one task node from list
without the lock protection. So that we could see from

Hi both,
Thanks for your patches. I tried to test your patches, first the 2nd
one, namely Hillf's patch, it's OK. Then when I wanted to reproduce and
test Cong's patch, it failed to happen again.
I remember this bug happened randomly at the very beginning,
just after kernel compiling it

Hi Tianhong,
I applied your patch and execute below cmd.
Then keyboard inputting problems happened,

This logic is not simple to understand so that making separate function

Currently, the freelist of a slab consist of unsigned int sized indexes.
Most of slabs have less number of objects than 256, since restriction
for page order is at most 1 in default configuration. For example,
consider a slab consisting of 32 byte sized objects on two continous
pages. In this

Now, the size of the freelist for the slab management diminish,
so that the on-slab management structure can waste large space
if the object of the slab is large.
Consider a 128 byte sized slab. If on-slab is used, 31 objects can be
in the slab. The size of the freelist for this case would be 31
This patchset implements byte sized indexes for the freelist of a slab.
Currently, the freelist of a slab consist of unsigned int sized indexes.
Most of slabs have less number of objects than 256, so much space is wasted.
To reduce this overhead, this patchset implements byte sized indexes for
Return directly if memory allocation fails. There is no need
of dma_free_coherent().

We tend to batch the used adding and signaling in vhost_zerocopy_callback()
which may result more than 100 used buffers to be updated in
vhost_zerocopy_signal_used() in some cases. So switch to use
vhost_add_used_and_signal_n() to avoid multiple calls to
vhost_add_used_and_signal(). Which means
We used to poll vhost queue before making DMA is done, this is racy if vhost
thread were waked up before marking DMA is done which can result the signal to
be missed. Fix this by always polling the vhost thread before DMA is done.

As Michael point out, We used to limit the max pending DMAs to get better cache
utilization. But it was not done correctly since it was one done when there's no
new buffers submitted from guest. Guest can easily exceeds the limitation by
keeping sending packets.
So this patch moves the check into

Currently, even if the packet length is smaller than VHOST_GOODCOPY_LEN, if
upend_idx != done_idx we still set zcopy_used to true and rollback this choice
later. This could be avoided by determining zerocopy once by checking all
conditions at one time before.
