Kconfig is tricky. We face a build error with CONFIG_BLOCK=n with UBIFS_FS_ENCRYPTION enabled.
UBIFS file encryption does "select FS_ENCRYPTION" just like ext4 and f2fs.
This will enable ENCRYPTION even when no block support is available.

I can make UBIFS depend on BLOCK as intermediate fix.
But the real fix is this patch.

Thanks,
