fscrypt_par...y_encryption(9)

💖 NAME 💖

okay so bestie, this whole page is about fscrypt_parse_test_dummy_encryption — the function that parses the test_dummy_encryption mount option. that's the vibe. also hi, this is from the Kernel API Manual, and the page title is fscrypt_par...y_encryption(9) (yes the ... is literally in the title, not me being dramatic 💅).

✨ SYNOPSIS ✨

int fscrypt_parse_test_dummy_encryption (const struct fs_parameter
       *param , struct fscrypt_dummy_policy *dummy_policy );

🎀 ARGUMENTS 🎀

• param — literally the mount option. that's the whole arg, no cap.
• dummy_policy — (input/output) the place to write the dummy policy that will result from parsing the option. zero-initialize this, fr fr. if a policy is already set here (because test_dummy_encryption was given multiple times), then this function will verify that the policies are the same. the way it checks for consistency — obsessed.

🌸 RETURN 🌸

• 0 on success — slay.
• -EINVAL if the argument is invalid — not iconic.
• -EEXIST if the argument conflicts with one already specified — conflict alert.
• or -ENOMEM — memory said no 😭.
