Subject: Re: [PATCH] nptl: Use SA_RESTART for SIGCANCEL handler
Date: Tue, 22 Jun 2021 21:51:29 +0200 [thread overview]
Message-ID: <87bl7xada6.fsf@oldenburg.str.redhat.com> (raw)
In-Reply-To: <ebf0c7b3-7ea7-7b97-667e-d46347eee0cc@linaro.org> (Adhemerval Zanella's message of "Tue, 22 Jun 2021 16:50:09 -0300")
* Adhemerval Zanella:

Suggest: “some CIFS [versions]”
Rest looks okay to me, thanks.
