Subject: [PATCH 01/10] staging: erofs: fix `trace_erofs_readpage' position
Date: Tue, 20 Nov 2018 22:34:16 +0800 [thread overview]
Message-ID: <20181120143425.43637-2-gaoxiang25@huawei.com> (raw)
In-Reply-To: <20181120143425.43637-1-gaoxiang25@huawei.com>
`trace_erofs_readpage' should be placed in .readpage()
rather than in the internal `z_erofs_do_read_page'.
Fixes: 284db12cfda3 ("staging: erofs: add trace points for reading zipped data")
