I also have CONFIG_EXT4_USE_FOR_EXT23=y , hower I use it only to mount /boot
(ext3), rest of file systems are ext4. So it XT4_USE_FOR_EXT23=y is not an
issue IMHO.

Your call trace is somehow similar that it is also in ext4_evict_inode code.
However deadlock is detected in simpler condition (single CPU, with some bug
due re-aquiring lock by same task).
