nilfs_ioctl_trim_fs(9)

📦 version 7.3.1, in nixpkgs unstable

okay bestie, welcome to the nilfs_ioctl_trim_fs(9) page from the Kernel API Manual — this is your kernel ioctl bestie speaking ✨

🎀 NAME 🎀

nilfs_ioctl_trim_fs — trim ioctl handle function. That's the whole vibe: it's the handler for the <rainbow>FITRIM</rainbow> ioctl, and it's literally giving kernel main character energy 👑

✨ SYNOPSIS ✨

int nilfs_ioctl_trim_fs (struct inode *inode , void __user *argp );

🌸 ARGUMENTS 🌸

  • inode — the inode object. literally the inode bestie 🫶
  • argp — pointer on argument from userspace. the userspace argument pointer walks in and says hi 💅

💖 DESCRIPTION 💖

nilfs_ioctl_trim_fs is the <rainbow>FITRIM</rainbow> ioctl handle function. No cap. It checks the arguments from userspace and calls nilfs_sufile_trim_fs, which performs the actual trim operation.

so yeah — nilfs_ioctl_trim_fs is the one doing the argument check, and nilfs_sufile_trim_fs is the one actually doing the trim operation. periodt 🧚

🔥 RETURN 🔥

0 on success, or a negative error code on failure. if it's 0, slay; if it's negative, the error code is telling you what went wrong 💀
