🎀 pcpu_dump_alloc_info(9) 🎀

okay so bestie, welcome to the Kernel API Manual page for pcpu_dump_alloc_info 💖 this one is lowkey niche but highkey useful if you're already deep in percpu lore. let's get into it, iykyk ✨

✨ NAME ✨

• pcpu_dump_alloc_info — print out information about pcpu_alloc_info

🦋 SYNOPSIS 🦋

void pcpu_dump_alloc_info (const char *lvl , const struct
       pcpu_alloc_info *ai );

💖 ARGUMENTS 💖

• lvl — loglevel. That's the loglevel, periodt.
• ai — allocation info to dump. This is the allocation info it's gonna dump.

🌸 DESCRIPTION 🌸

okay so the whole vibe: it prints out information about ai using loglevel lvl. That's it, that's the function. No cap. It is literally a dump-info moment for the allocation info, and the manual is not hiding extra lore from us. 💅
