📦 version 7.3.1, in nixpkgs unstable

💖 debugfs_create_x64(9) 💖

okay so bestie, welcome to the Kernel API Manual, section 9 — this is the page for debugfs_create_x64, and honestly? it's giving "small but mighty" ✨

🌸 NAME 🌸

debugfs_create_x64 — creates a debugfs file that reads and writes an unsigned 64-bit value. that's it, that's the whole gig 💅

🎀 SYNOPSIS 🎀

void debugfs_create_x64 (const char *name , umode_t mode , struct dentry
*parent , u64 *value );

no cap, that's the whole signature 🫶

🦋 ARGUMENTS 🦋

okay so here's who's who in this little friend group:

  • name — a pointer to a string holding the name of the file you're about to create. name your child wisely 💖
  • mode — the permission that the file should have. yes, that kind of permission, the file-mode kind 🌈
  • parent — a pointer to the parent dentry for this file. if you set it, it should be a directory dentry, okay? and if this parameter is NULL, then the file gets created in the root of the debugfs filesystem — main character energy, no parent, just vibes 👑
  • value — a pointer to the variable that the file should read from and write to. this is the actual data bestie, the whole point 🍓
