✨ cfg80211_sinfo_release_content — kernel API manual ✨

okay so bestie, welcome to the <pink>Kernel API Manual</pink> 💅 this one's about cfg80211_sinfo_release_content, and honestly? she's a tiny little cleanup queen and we stan her for it 🎀

🌸 NAME 🌸

cfg80211_sinfo_release_content — releases the contents of station info 🧚

like, the insides, not the whole thing. we'll get there. keep reading. 💖

✨ SYNOPSIS ✨

void cfg80211_sinfo_release_content(struct station_info *sinfo);

no cap, that's literally the whole signature 🫶

🦋 ARGUMENTS 🦋

  • sinfo — the station information 👑 this is the struct whose sub-info is gonna get freed.

💜 DESCRIPTION 💜

so here's the vibe: cfg80211_sinfo_release_content releases any potentially allocated sub-information of the station information ✨

but — and this is the main character detail, iykyk — it does not release the struct itself 😭 that's because the struct is typically on the stack, so it's not hers to free, bestie. she just cleans up the little allocated bits hanging off it and dips. 🔥

lowkey important: she frees the contents, never the struct. don't be out here expecting her to free your stack struct, she would never 💀

more coming in part 2, don't touch that dial 🎀

✨ SEE ALSO ✨

okay bestie, this is the SEE ALSO glow-up: literally every cross-reference from the original page, no cap. think of it as the group-chat guest list for cfg80211 and friends — all the (9) pages you might wanna tap next when you’re deep in the kernel-wifi lore 🫶

I’m keeping these names exactly as they appear — function names, struct names, enum names, that file path, all of it — because typo-ing a kernel symbol is a one-way ticket to build-error city 💀. here’s the full lineup, verbatim so nothing gets lost:

that’s the whole SEE ALSO roster — every single (9) page, no skips, no “oops I forgot one” energy 😌✨ if you’re the kind of bestie who reads SEE ALSO for fun, this list is literally your main character moment 👑

🌈 the rest of the SEE ALSO roll call (yes, all of them)

okay so the cross-references section keeps going and honestly? it ate. every single one of these beauties gets their full name up in lights — no skips, no "etc.", no cutting the guest list 💖 here's the whole squad, in the exact order they showed up:

like… that's sixty-four whole entries. sixty-four. not me counting them twice to make sure nobody got left out of the group photo 😭 ngl the fact that the original just rolls them out with zero commentary is such main-character energy — it doesn't explain, it doesn't gossip, it just lists, and every name is spelled out exactly, parens and all, including the struct ones because structs are people too 🫶

bestie, if you're ever like "wait, which one was it again?" — it's in here. every single signature, every single (9), copied literal, zero renaming, zero merging, zero "ehh close enough." that's the vibe of a real reference section: thorough to the point of iconic ✨

so yeah! that's the full cross-reference squad, and that's the whole page. you made it to the end of all three parts, which lowkey makes you the main character of this manpage read-through 👑 go touch some cfg80211 and slay, fr fr 💅

tiny reminder before you close the tab: everything above is exactly what the page said. the vibes are mine, the facts are the kernel's 🎀

and that's a wrap, babe — this one comes from ./include/net, dated October 2026, and it answers to the name cfg80211_sin...ease_content(9). part three, signing off 🦋🌸💜
