sysfs_break...e_protection(9)

okay so welcome to the Kernel API Manual, bestie — you're on the sysfs_break...e_protection(9) page, and it's giving “tiny but important.” 💅

💖 NAME 💖

sysfs_break_active_protection — break "active" protection. periodt.

✨ SYNOPSIS ✨

struct kernfs_node * sysfs_break_active_protection (struct kobject *kobj
, const struct attribute *attr );

🎀 ARGUMENTS 🎀

• kobj — the kernel object that attr is associated with. 🫶
• attr — the attribute to break the "active" protection for. ✨

🦋 DESCRIPTION 🦋

okay so here's the tea, bestie: with sysfs, just like kernfs, deletion of an attribute is postponed until all active .show and .store callbacks have finished. unless this function is called, that's the rule. So this function is useful in methods that implement self deletion. no cap, that's literally the whole point. 😭

vibe check: the deletion postponing is the whole situation unless you call this function — so don't miss the “unless this function is called” part, iykyk. 🧚
