drbd_chk_io_error(9)

💖 drbd_chk_io_error(9) 💖

okay bestie, this is a Kernel API Manual page, and it is short, specific, and very “read the code, babe.” It handles the on_io_error setting, and that is literally the main-character assignment here. Let’s go. 💅

✨ NAME ✨

drbd_chk_io_error — handles the on_io_error setting; it should be called from all io completion handlers. That’s the whole vibe. 🫶

🎀 SYNOPSIS 🎀

so the call looks like this, spaces and all:

drbd_chk_io_error (m , e , f );

🌸 ARGUMENTS 🌸

• m — -- undescribed --
• e — -- undescribed --
• f — -- undescribed --

and yeah, the manpage literally says -- undescribed -- for all three. mysterious icon behavior, but I am not inventing lore. 🙈

🦋 DESCRIPTION 🦋

the description is a see-also girlie: it points you at drbd_main.c:after_state_ch, specifically this condition:

if (os.disk > D_FAILED && ns.disk == D_FAILED)

that’s it. that’s the description. no extra paragraphs, no side quests. 💀
