Hi Greg, please apply the following two cc-stable patches to 4.14-stable. Ryusuke Konishi (2): nilfs2: fix lockdep warnings in page operations for btree nodes nilfs2: fix lockdep warnings during disk space reclamation During testing nilfs2 filesystem with stable trees, I encountered a lockdep warning followed by a kernel panic (by panic_on_warn) only in 4.14-stable. I found that the cause was the lack of these patches which are applied to other newer stable trees. I guess they were dropped since the first patch was not applicable as is due to a pagevec change. After I manually applied them to 4.14, the panic and lockdep warning have gone. So, I believe these should be backported to 4.14-stable as well.
