hash_for_each_safe(9)

✨ NAME ✨

okay bestie, meet hash_for_each_safe — the one that helps you iterate over a hashtable safe against removal of hash entry. 💅 this is the hash_for_each_safe(9) page from the Kernel API Manual, and it's giving “removal-safe loop, no cap.” 🫶

🎀 SYNOPSIS 🎀

here's the exact spell, copy it character for character:

hash_for_each_safe (name , bkt , tmp , obj , member );

💅 ARGUMENTS 💅

• name — the hashtable to iterate. slay, that's your table. ✨
• bkt — an integer to use as bucket loop cursor. it keeps the bucket loop moving, iykyk. 🔥
• tmp — a struct used for temporary storage. literally the temp bestie holding space. 🎀
• obj — the type * to use as a loop cursor for each entry. main character loop cursor energy. 👑
• member — the name of the hlist_node within the struct. yes, that exact member. 💖
