cifs_to_posix_acl(9)

✨ NAME ✨

okay so bestie, welcome to the cifs_to_posix_acl(9) page from the Kernel API Manual 💖 this one is literally about one job: copy cifs ACL format to POSIX ACL format. no cap.

🌸 SYNOPSIS 🌸

int cifs_to_posix_acl (struct posix_acl **acl , char *src , const int
       acl_type , const int size_of_data_area );

🎀 ARGUMENTS 🎀

• acl — ACLs returned in POSIX ACL format. this is where the converted glow-up goes ✨
• src — ACLs in cifs format. the raw material, bestie 🫶
• acl_type — type of POSIX ACL requested. you gotta tell it which flavor you want 💅
• size_of_data_area — size of SMB we got. yes, that's the whole note 📏

🦋 DESCRIPTION 🦋

okay so this function converts ACLs from cifs format to POSIX ACL format — it's giving translator era 🌈.

but here's the plot twist: if acl is NULL, then the size of the buffer required to store POSIX ACLs in their uapi format is returned. so it's lowkey a size-checker in that case, periodt 💅.
