We can technically enable inode_cache in the same way as relocation.
However, inode_cache is rarely used and the man page discourage using it.
So, let's just disable it for now.

Don't worry about the inode_cache mount option, it's been deprecated
as of commit b547a88ea5776a8092f7 and will be removed in 5.11.

Thanks. I'll drop this one in the next version.
