okay so this is a page from the Kernel API Manual bestie, and it's all about ibmvscsis_check_init_msg β one function, one job, and honestly it eats β¨
πΈ NAME πΈ
ibmvscsis_check_init_msg β check if the init message is valid π
π¦ SYNOPSIS π¦
long ibmvscsis_check_init_msg (struct scsi_info *vscsi , uint *format );
π ARGUMENTS π
vscsiβ pointer to our adapter structure, like yes this is us, this is our moment πformatβ pointer to where we return the format of the Init Message, if any. And listen: if there's literally no Init Message in the queue, it gets set toUNUSED_FORMAT. no message, no format, periodt π
β¨ DESCRIPTION β¨
so the vibe check here is simple: this function checks whether an initialize message got queued by the initiatior after the queue was created and before the interrupt was enabled π«Ά like it's checking the timeline, the sequencing, the whole order of events ngl
EXECUTION ENVIRONMENT: Process level only, interrupt lock held π β do not try this anywhere else, bestie, it's giving "read the room" π
