Subject: Re: [PATCH 3/3] htl: move pthread_self info libc.
Date: Wed, 5 Apr 2023 01:35:18 +0200	[thread overview]
Message-ID: <20230404233518.xtl7zqq44ae2fwgz@begin> (raw)
In-Reply-To: <20230318095826.1125734-4-gfleury@disroot.org>

Applied, but see the modification I made: since pthread_self was already
there in libc's forward.c under version 2.21, there is really no reason
to introduce a 2.38 version, and instead just plug compatibility under
version 2.21.

But that's only for forward.c functions. For others you'll indeed need
to introduce a 2.38 version when adding the symbol to libc.

Thanks!
