Subject: [PATCH 03/10] Revert "signal: don't allow sending any signals to PF_IO_WORKER threads"
Date: Fri, 26 Mar 2021 09:51:16 -0600 [thread overview]
Message-ID: <[email protected]> (raw)
In-Reply-To: <[email protected]>
This reverts commit 5be28c8f85ce99ed2d329d2ad8bdd18ea19473a5.
IO threads now take signals just fine, so there's no reason to limit them
specifically. Revert the change that prevented that from happening.
