π wait_for_space(9) β Kernel API Manual, bestie edition β¨
Okay so real talk: this is wait_for_space from section 9 of the Kernel API Manual, and she is exactly what her name says. A little helper that patiently waits for room in a ring buffer. Iconic behavior honestly. Let's get into it π«Ά
β¨ NAME β¨
wait_for_space β check ring buffer free space. That's it, that's the whole gig π
πΈ SYNOPSIS πΈ
int wait_for_space (struct fb_info *info , u32 space );
Literally just that. She takes two things and returns an int. No cap π§
π ARGUMENTS π
infoβ okay so the manpage itself says -- undescribed -- and I'm not gonna lie to you bestie, that's all we get π the original page gives us nothing here, so I'm giving you nothing here either. We respect the source. She's a mystery. Main character energy fr.spaceβ the amount of ringbuffer space needed, and it's measured in bytes. That's the whole vibe check right there β¨
π¦ DESCRIPTION π¦
So what does she do? The function waits until a free space from the ringbuffer is available. That's the tea, that's the function, periodt π
Like, you want space in the ringbuffer? She'll wait for it. The space you passed in β in bytes β is the amount she's waiting on. Standing there. Being patient. An absolute queen π

ngl if you got here looking for lore about info, the page genuinely says -- undescribed --. Not my fault bestie, I'm just the messenger π
