[0/7] Remove fs specific fscrypt and fsverity build config options

Message

Chandan Rajendra Nov. 19, 2018, 5:23 a.m. UTC

As a first step to avoid copy-pasting common code across filesystems
which implement fscrypt/fsverity, this commit removes filesystem
specific build config option (CONFIG_EXT4_FS_ENCRYPTION,
CONFIG_EXT4_FS_VERITY, CONFIG_F2FS_FS_ENCRYPTION and
CONFIG_F2FS_FS_VERITY) and replaces it with build options
(CONFIG_FS_ENCRYPTION and CONFIG_FS_VERITY) whose values affect all
the filesystems making use of fscrypt and fsverity. This is done in
order to have a common code base for implementing "post read"
processing across filesystems.

Changelog:
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.

Chandan Rajendra (7):
  ext4: use IS_ENCRYPTED() to check encryption status
  f2fs: use IS_ENCRYPTED() to check encryption status
  fscrypt: Remove filesystem specific build config option
  Add S_VERITY and IS_VERITY()
  ext4: use IS_VERITY() to check inode's fsverity status
  f2fs: use IS_VERITY() to check inode's fsverity status
  fsverity: Remove filesystem specific build config option
