Subject: [PATCH for-next 5/5] erofs: set iowait for sync decompression
Date: Tue, 8 Oct 2019 20:56:16 +0800 [thread overview]
Message-ID: <20191008125616.183715-5-gaoxiang25@huawei.com> (raw)
In-Reply-To: <20191008125616.183715-1-gaoxiang25@huawei.com>
For those tasks waiting I/O for sync decompression,
they should be better marked as IO wait state.
