Chandan, it appears the problem is UBIFS_FS selecting BLOCK. It's actually not necessary because now the parts of fs/crypto/ that depend on BLOCK are separated out into a separate file fs/crypto/bio.c that is only compiled with CONFIG_BLOCK. So how about just removing the selection of BLOCK from fs/ubifs/Kconfig: select BLOCK if FS_ENCRYPTION - Eric
