🦋 DESCRIPTION 🦋

💅 /proc/pid/wchan (since Linux 2.6.0) 💅

The way this file is literally holding the symbolic name that corresponds to the location in the kernel where the process is sleeping. 😴 no cap, it's the kernel's little "currently asleep right here" tag for a process.

Who gets to peek? Access is governed by a ptrace access mode PTRACE_MODE_READ_FSCREDS check — go see ptrace(2). 🔐
