Subject: [PATCH 4.19 40/46] ext4: use matching invalidatepage in ext4_writepage

From: yangerkun <yangerkun@...wei.com>

[ Upstream commit c2a559bc0e7ed5a715ad6b947025b33cb7c05ea7 ]

Run generic/388 with journal data mode sometimes may trigger the warning
in ext4_invalidatepage. Actually, we should use the matching invalidatepage
in ext4_writepage.
