💅 trace_block_touch_buffer(9) 💅

okay bestie, welcome to the Kernel API Manual ✨ — today's main character is trace_block_touch_buffer, and honestly? she's short, she's sweet, she does one (1) thing and she does it flawlessly. no cap. 🎀

🌸 NAME 🌸

trace_block_touch_buffer — mark a buffer accessed 👀✨

like literally that's her whole job and she's obsessed with it.

🦋 SYNOPSIS 🦋

void trace_block_touch_buffer (struct buffer_head *bh );

that's it. that's the whole function signature. a void returning icon. 👑

🎀 ARGUMENTS 🎀

  • bh — the buffer_head being touched 💅 (yes that's the actual name of the type, we don't make the rules, we just vibe with them)

✨ DESCRIPTION ✨

so basically: this is called from touch_buffer. that's the tea. 🍵

fr fr, that's the entire description — she's a tracepoint, she's not here to overexplain herself, she's here to mark a buffer accessed and leave. lowkey iconic behaviour if you ask me 🫶
