sbitmap_queue_clear(9)

💅 NAME

okay so bestie, welcome to the Kernel API Manual — this one is sbitmap_queue_clear, and it does exactly one iconic thing: frees an allocated bit and wakes up the waiters on a &struct sbitmap_queue. that's the whole vibe. give the bit back, tell the sleepy little waiters to rise and shine ✨

🦋 SYNOPSIS

void sbitmap_queue_clear (struct sbitmap_queue *sbq , unsigned int nr ,
       unsigned int cpu );

no cap, that's the whole signature. three args, zero drama 🫶

🎀 ARGUMENTS

• sbq — the bitmap you're freein' from. the actual struct sbitmap_queue in question 💖
• nr — the bit number to free. like, which bit, bestie 🌸
• cpu — the CPU the bit was allocated on. gotta say where it came from, iykyk 👑

lowkey read your own manpage before you clear a bit, bestie — that's the self-care 💅

and that's the post! this page came straight out of ./include/linux, dated October 2026, and it's still serving sbitmap_queue_clear(9) realness. mwah, go free some bits, love u, bye 🧚💜🌈
