PS: Since I have access to only to x86 and ppc64le machines, I haven't tested the defconfig files for other architectures. Changelog: V1 -> V2: 1. Address the following review comments provided by Eric Biggers, - In ext4_should_use_dax(), Use ext4_test_inode_flag() to check for fscrypt/fsverity status of an inode. - Update documentation associated with fscrypt & fsverity to refer to CONFIG_FS_ENCRYPTION and CONFIG_FS_VERITY build flags. - Remove filesystem specific fscrypt build configuration from defconfig files. - Provide a list of supported filesystems for CONFIG_FS_ENCRYPTION and CONFIG_FS_VERITY build flags. - Update comment describing S_VERITY flag. 2. Remove UBIFS specific encryption build option and make use of the generic CONFIG_FS_ENCRYPTION flag. RFC -> V1: 1. Add a new patch to implement S_VERITY/IS_VERITY(). 2. Split code that replaces filesystem specific routines with generic IS_ENCRYPTED() and IS_VERITY() calls into separate patches.
