Anyone in the DPDK Tech Board,
I was online last Wednesday for the DPDK tech board meeting, but no one else
were there, so I guess it was cancelled.
Is the next tech board meeting still scheduled for Wednesday April 4th at 3 PM
UTC (17:00 CEST), or is it today?
And is it still on https://meet.
Now that all locks in this library are annotated, we can enable the
check.

clang offers some thread safety checks, statically verifying that locks
are taken and released in the code.
To use those checks, the full code leading to taking or releasing locks
must be annotated with some attributes.
Wrap those attributes into our own set of macros.

vhost internals involves multiple locks to protect data access by
multiple threads.
This series is a try at using clang thread safety checks [1] to catch
issues during compilation: EAL spinlock and rwlock are annotated and
vhost code is instrumented so that clang can statically check
correctness.

AFAICT, dmadev can be anything from part of a CPU to a completely
