  From: Dexuan Cui 

  We can concurrently try to open the same sub-channel from 2 paths:

  path #1: vmbus_onoffer() -> vmbus_process_offer() -> handle_sc_creation().
  path #2: storvsc_probe() -> storvsc_connect_to_vsp() ->
 -> storvsc_channel_init() -> handle_multichannel_storage() ->
 -> vmbus_are_subchannels_present() -> handle_sc_creation().

  They conflict with each other, but it was not an issue before the recent
  commit

  From: Dexuan Cui 

  We can concurrently try to open the same sub-channel from 2 paths:

  path #1: vmbus_onoffer() -> vmbus_process_offer() -> handle_sc_creation().
  path #2: storvsc_probe() -> storvsc_connect_to_vsp() ->
 -> storvsc_channel_init() -> handle_multichannel_storage() ->
 -> vmbus_are_subchannels_present() -> handle_sc_creation().

  They conflict with each other, but it was not an issue before the recent
  commit ae6935ed7d42 ("vmbus: split ring buffer allocation from open"),
  because at the beginning of vmbus_open() we checked newchannel->state so
  only one path could succeed, and the other would return

2018-11-26 Thread Joshua R. Poulson

Issue found: on L80v2 the kernel is allocating IRQs outside of NUMA0,
but all of the NVME disks on L80v2 are on NUMA0. Looking for a relevant
patch for this.

  Drivers: hv: vmbus: Remove x86-isms from arch independent drivers
  
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/drivers/hv?h=next-20181126=4a5f3cde4d51c7afce859aed9d74d197751896d5

  From: Dexuan Cui 

  We can concurrently try to open the same sub-channel from 2 paths:

  path #1: vmbus_onoffer() -> vmbus_process_offer() -> handle_sc_creation().
  path #2: storvsc_probe() -> storvsc_connect_to_vsp() ->
 -> storvsc_channel_init() -> handle_multichannel_storage() ->
 -> vmbus_are_subchannels_present() -> handle_sc_creation().

  They conflict with each other, but it was not an issue before the recent
  commit ae6935ed7d42 ("vmbus: split ring buffer allocation from open"),
  because at the beginning of vmbus_open() we checked newchannel->state so
  only one path could succeed, and the other would

  From: Dexuan Cui 

  We can concurrently try to open the same sub-channel from 2 paths:

  path #1: vmbus_onoffer() -> vmbus_process_offer() -> handle_sc_creation().
  path #2: storvsc_probe() -> storvsc_connect_to_vsp() ->
 -> storvsc_channel_init() -> handle_multichannel_storage() ->
 -> vmbus_are_subchannels_present() -> handle_sc_creation().

  They conflict with each other, but it was not an issue before the recent
  commit

  From: Dexuan Cui 

  We can concurrently try to open the same sub-channel from 2 paths:

  path #1: vmbus_onoffer() -> vmbus_process_offer() -> handle_sc_creation().
  path #2: storvsc_probe() -> storvsc_connect_to_vsp() ->
 -> storvsc_channel_init() -> handle_multichannel_storage() ->
 -> vmbus_are_subchannels_present() -> handle_sc_creation().

  They conflict with each other, but it was not an issue before

  We can concurrently try to open the same sub-channel from 2 paths:

  path #1: vmbus_onoffer() -> vmbus_process_offer() -> handle_sc_creation().
  path #2: storvsc_probe() -> storvsc_connect_to_vsp() ->
 -> storvsc_channel_init() -> handle_multichannel_storage() ->
 -> vmbus_are_subchannels_present() -> handle_sc_creation().

  They conflict with each other, but it was not an issue

  From: Dexuan Cui 

  We can concurrently try to open the same sub-channel from 2 paths:

  path #1: vmbus_onoffer() -> vmbus_process_offer() -> handle_sc_creation().
  path #2: storvsc_probe() -> storvsc_connect_to_vsp() ->
 -> storvsc_channel_init() -> handle_multichannel_storage() ->
 -> vmbus_are_subchannels_present() -> handle_sc_creation().

  They conflict with each other, but it was not an issue
