Why was the XTS tweak initialization changed in commit 0b81d0779072 ("fs crypto:
move per-file encryption from f2fs tree to fs/crypto")?
Old code:
memcpy(xts_tweak, &index, sizeof(index));
memset(&xts_tweak[sizeof(index)], 0,
F2FS_XTS_TWEAK_SIZE - sizeof(index));
New code:
memcpy(xts_tweak, &inode->i_ino, sizeof(index));
memset(&xts_tweak[sizeof(index)], 0,
FS_XTS_TWEAK_SIZE - sizeof(index));
Now the XTS tweak is the same for all pages of each inode.
