ksmbd_tcp_readv(9)

✨ NAME ✨

okay so bestie, ksmbd_tcp_readv(9) is from the Kernel API Manual, and it's literally the function that reads data from a socket into the given iovec. no cap, that's the whole vibe. 💅

🌸 SYNOPSIS 🌸

here's the exact signature, keep it cute and character-for-character:

int ksmbd_tcp_readv (struct tcp_transport *t , struct kvec *iov_orig ,
       unsigned int nr_segs , unsigned int to_read , int max_retries );

🎀 ARGUMENTS 🎀

• t — TCP transport instance, aka the transport bestie in question. 🫶
• iov_orig — base IO vector, the starter iovec, periodt.
• nr_segs — number of segments in base iov. yes, count them. ✨
• to_read — number of bytes to read from socket. that's the goal. 🎯
• max_retries — maximum retry count. the patience meter. 😭

🔥 RETURN 🔥

on success, it returns the number of bytes read from socket. otherwise, it returns an error number. so either you get the byte count or you get the error tea. 💀✨
