Subject: [PATCH 01/11] io-wq: fix worker counting after worker received exit signal
Date: Fri, 9 Jun 2023 20:20:21 +0800 [thread overview]
Message-ID: <[email protected]> (raw)
In-Reply-To: <[email protected]>
From: Hao Xu <[email protected]>
acct->nr_workers should be decremented when we break the loop in
io_wq_worker().
Fixes: 78f8876c2d9f ("io-wq: exclusively gate signal based exit on get_signal() return")
Signed-off-by: Hao Xu <[email protected]>
