Hi Ted, After merging the ext4 tree, today's linux-next build (powerpc ppc64_defconfig) failed like this: fs/ext4/file.c: In function 'ext4_file_mmap': fs/ext4/file.c:226:3: error: implicit declaration of function 'ext4_get_encryption_info' [-Werror=implicit-function-declaration] int err = ext4_get_encryption_info(inode); ^ fs/ext4/super.c: In function 'ext4_clear_inode': fs/ext4/super.c:958:19: error: 'struct ext4_inode_info' has no member named 'i_crypt_info' if (EXT4_I(inode)->i_crypt_info) ^ Caused by commit ef8a5d07c606 ("ext4 crypto: reorganize how we store keys in the inode"). This build has CONFIG_EXT4_FS_ENCRYPTION not set. I have used the ext4 tree from next-20150506 for today. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au
