ENUM BLOCK_STATE(9)

📦 version 7.3.1, in nixpkgs unstable

🎀 enum block_state(9) 🎀

okay bestie, welcome to the Kernel API Manual — we're looking at enum block_state(9) today and honestly it's a short one but it's lowkey important, so let's go 💅

✨ NAME ✨

enum block_state — the blocking state, fr fr

✨ SYNOPSIS ✨

enum block_state {
    NON_BLOCKING ,
    BLOCKING

};

✨ Constants ✨

bestie there are literally two of them, and they are exactly what they sound like:

  • NON_BLOCKING — non blocking 🦋
  • BLOCKING — blocking 💀

that's it. that's the whole list. iconic minimalism honestly 👑

✨ Description ✨

okay so here's the tea ☕ — these states exist for ioctls that need to wait for a response from firmware. and the way that works means they probably require sleep 😴

so like, if you're the one holding one of these states, know that you might be going nite-nite for a sec waiting on the firmware to text back. plan accordingly 🫶

✨ SEE ALSO ✨

okay this section is giving main character energy because there are SO many friends here 🌈 first up, the kernel file:

  • Kernel file ./drivers/scsi/mpt3sas/mpt3sas_ctl.c

and now the whole group chat 💖:

like, that's the whole friend group and every single one of them slayed 🔥 go read them, iykyk 💜

ok that's the page bestie, go forth and block responsibly 🧚‍♀️✨

and finally, the cute little sign-off 🎀 — this page comes to you from ./drivers/scsi/mpt3sas, dated October 2026, and it's enum block_state(9) all day. periodt 💅
