Could you please help to fix that as below in your dev branch directly?

"Inconsistent i_blocks, ino:%lu, iblocks:%llu",
inode->i_ino, (unsigned long long)inode->i_blocks)

It looks that we need to fix below commits as well:

f2fs: fix to avoid panic in dec_valid_block_count()
f2fs: fix to avoid panic in dec_valid_node_count()

Thanks,
