Hello,
Ran into an odd bug that I am unsure what the solution is. Tested a few
kernels versions and they all fail the same.
FUNCTION_GRAPH_FP_TEST was enabled with 953f534a7ed6 ("ARM: ftrace:
enable HAVE_FUNCTION_GRAPH_FP_TEST"). This test fails when
UNWINDER_FRAME_POINTER is enabled.

iommu allocations should be accounted in order to allow admins to
monitor and limit the amount of iommu memory.

Hello,
DESCRIPTION
This patchset fixes old problem with hungup of both rx/tx sides and adds
test for it. This happens due to non-default SO_RCVLOWAT value and
deferred credit update in virtio/vsock. Link to previous old patchset:
Send credit update message when SO_RCVLOWAT is updated and it is bigger
than number of bytes in rx queue. It is needed, because 'poll()' will
wait until number of bytes in rx queue will be not smaller than
SO_RCVLOWAT, so kick sender to send more data. Otherwise mutual hungup
for tx/rx is
Do not return if transport callback for SO_RCVLOWAT is set (only in
error case). In this case we don't need to set 'sk_rcvlowat' field in
each transport - only in 'vsock_set_rcvlowat()'. Also, if 'sk_rcvlowat'
is now set only in af_vsock.c, change callback name from 'set_rcvlowat'
to
