fscrypt_con...or_new_inode(9)

✨ NAME ✨

okay bestie, this is the Kernel API Manual page for fscrypt_con...or_new_inode(9), and the actual function is fscrypt_context_for_new_inode — create an encryption context for a new inode. periodt 💅

✨ SYNOPSIS ✨

int fscrypt_context_for_new_inode (void *ctx , struct inode *inode );

✨ ARGUMENTS ✨

• ctx — where context should be written. that's the spot, bestie 🫶
• inode — inode from which to fetch policy and nonce. she's the source of truth ✨

✨ DESCRIPTION ✨

Given an in-core "prepared" (via fscrypt_prepare_new_inode) inode, generate a new context and write it to ctx. lowkey that's the whole move 💖

ctx _must_ be at least FSCRYPT_SET_CONTEXT_MAX_SIZE bytes. not optional, not "close enough", fr fr — give her the full size she needs.

✨ RETURN ✨

size of the resulting context or a negative error code. so you either get the size, or you get a negative error code situation 😭
