Subject: [patch 14/14] nilfs2: make splice write available again
Date: Tue, 09 Feb 2021 13:42:36 -0800 [thread overview]
Message-ID: <20210209214236.pDQfcjKyd%akpm@linux-foundation.org> (raw)
In-Reply-To: <20210209134115.4d933d446165cd0ed8977b03@linux-foundation.org>

Subject: nilfs2: make splice write available again
Since 5.10, splice() or sendfile() to NILFS2 return EINVAL. This was
caused by commit 36e2c7421f02 ("fs: don't allow splice read/write without
explicit ops").
This patch initializes the splice_write field in file_operations, like
most file systems do, to restore the functionality.
