Subject: Re: [dpdk-dev] [PATCH 1/2] ethdev: make flow API primary/secondary process safe
Date: Mon, 19 Apr 2021 19:14:08 +0200
Message-ID: <1869905.GZgYhOu6rl@thomas> (raw)
In-Reply-To: <20210315192722.35490-2-stephen@networkplumber.org>

About the title, better to say "multi-process" and do not
commit on being completely safe for the whole API.
It is just fixing the mutex for multi-process,
and this mutex is for driver not being natively multi-thread.

The compilation fails on MinGW:
error: implicit declaration of function ‘pthread_mutexattr_init’

These lines must be sorted.
