klist_prev(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… NAME πŸ’…

klist_prev(9) β€” fresh from the Kernel API Manual β€” is the function that's here to Ante up prev node in list. That's the whole name-drop, bestie. ✨

✨ SYNOPSIS ✨

struct klist_node * klist_prev (struct klist_iter *i );

πŸŽ€ ARGUMENTS πŸŽ€

  • i β€” the iterator structure. She's the main character you pass in, okay? πŸ’…

πŸ¦‹ DESCRIPTION πŸ¦‹

Okay so here's the literal sequence, no cap:

  1. First, grab the list lock. πŸ”’
  2. Decrement the reference count of the previous node, if there was one.
  3. Grab the prev node, increment its reference count, drop the lock, and return that prev node. 🫢

That's the whole flow β€” lock first, handle that previous node's refcount if it exists, then scoop up the prev node, bump its refcount, release the lock, and hand it back. Iconic. 🌸
