sysfs_create_groups(9)

💖 NAME 💖

okay bestie, welcome to the sysfs_create_groups(9) page from the Kernel API Manual ✨

sysfs_create_groups — given a directory kobject, create a bunch of attribute groups. periodt 💅

✨ SYNOPSIS ✨

the signature is giving:

int sysfs_create_groups (struct kobject *kobj , const struct
       attribute_group *const *groups );

🎀 ARGUMENTS 🎀

• kobj — the kobject to create the group on. literally where the group gets made, iykyk.
• groups — the attribute groups to create, NULL terminated. keep that terminator in mind, bestie 🫶

🦋 DESCRIPTION 🦋

okay so here's the tea: this function creates a bunch of attribute groups 🌸

if an error occurs when creating a group, all previously created groups will be removed, unwinding everything back to the original state when this function was called. not me doing a full rollback 😭 it will explicitly warn and error if any of the attribute files being created already exist. so yeah, that's a whole vibe check.

the return is 0 on success, or the error code from sysfs_create_group on failure. slay when it works, dramatic unwind when it doesn't 💀
