✨ freezing_slow_path(9) ✨

okay so bestie, welcome to freezing_slow_path(9) from the Kernel API Manual β€” yes it's a manual page, yes it's about the freezer, and yes we're gonna get through this together πŸ’–


🌸 NAME 🌸

freezing_slow_path β€” the slow path for testing whether a task needs to be frozen 🧊

like, there's a fast path and then there's this one. the vibes are "we're checking properly this time."


πŸŽ€ SYNOPSIS πŸŽ€

bool freezing_slow_path (struct task_struct *p );

it returns a bool, it takes one pointer, and it's giving very "small function, big responsibility" energy. πŸ‘‘


πŸ¦‹ ARGUMENTS πŸ¦‹

  • p β€” the task to be tested 🫢 like, the actual struct task_struct * we're asking about. that's the one.

⭐ DESCRIPTION ⭐

so here's the tea β˜• β€” this function gets called by freezing if freezer_active isn't zero, and it tests whether p needs to enter and stay in the frozen state. πŸ₯Ά

can be called under any context. any. context. no cap. 🌈

the freezers are responsible for ensuring the target tasks see the updated state β€” that part is on them, not on this function, so don't come for this function about it πŸ’…

ngl the whole point here is: this is the slow path, so it's doing the careful check. the fast path handled the easy cases already. 🧚
