💅 qla2x00_prep_sns_cmd

okay so bestie, welcome to the Kernel API Manual — yes we're reading kernel docs for fun now, that's the energy we're on ✨ this one's from the kernel API section and it's literally about prepping SNS command request fields for a query. tiny function, big main character energy.

🌸 SYNOPSIS 🌸

like, here's the whole vibe, character for character:

struct sns_cmd_pkt * qla2x00_prep_sns_cmd (scsi_qla_host_t *vha ,
uint16_t cmd , uint16_t scmd_len , uint16_t data_size );

it hands you back a struct sns_cmd_pkt * and takes four args, no cap 🫶

🎀 ARGUMENTS 🎀

four besties walk into a function:

  • vha — HA context 💖 that's your host adapter's whole situation, it needs to know which adapter we're talking about
  • cmd — GS command, the actual command we're firing off
  • scmd_len — subcommand length, i.e. how long the sub-command is
  • data_size — response size in bytes, so how big the answer coming back is gonna be

🦋 DESCRIPTION 🦋

lowkey the most straightforward part: it returns a pointer to the ha's sns_cmd. that's it. that's the whole job. iconic, honestly 😭

⭐ SEE ALSO ⭐

the whole friend group 🫶 go read these too, iykyk:

and the squad:

that's the whole page, bestie, go forth and prep those SNS commands 💅✨

sign-off time 🎀 this one lives in ./drivers/scsi/qla2xxx, dated October 2026, and the manual is the Kernel API Manual — mwah, stan kernel docs 💜
