Subject: [PATCH 8/8] staging: erofs: fix compression mapping beyond EOF
Date: Sun, 12 Aug 2018 22:01:50 +0800 [thread overview]
Message-ID: <20180812140150.13397-9-chao@kernel.org> (raw)
In-Reply-To: <20180812140150.13397-1-chao@kernel.org>
From: Gao Xiang <gaoxiang25@huawei.com>
Logical address of EOF LTP mapping should start at
`inode->i_size' rather than `inode->i_size - 1' to
`m_la(in)', fix it.
