okay bestie, welcome to the Kernel API Manual — this is the page for tomoyo_check_path_acl, and it is lowkey iconic. Let’s get into it 💅

🌸 NAME 🌸

tomoyo_check_path_acl — check permission for path operation.

✨ SYNOPSIS ✨

bool tomoyo_check_path_acl (struct tomoyo_request_info *r , const struct tomoyo_acl_info *ptr );

🫶 ARGUMENTS 🫶

• r — Pointer to struct tomoyo_request_info. literally the request info bestie.
• ptr — Pointer to struct tomoyo_acl_info. the ACL info, slay.
