+Subject: nilfs2: make splice write available again
+
+From: Joachim Henke <joachim.henke@t-systems.com>
+
+commit a35d8f016e0b68634035217d06d1c53863456b50 upstream.
+
+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.
