This patch will later appear in the mm-new branch at
git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm
Note, mm-new is a provisional staging ground for work-in-progress
patches, and acceptance into mm-new is a notification for others take
notice and to finish up reviews. Please do not hesitate to respond to

Subject: mm: vmscan: add PIDs to vmscan tracepoints
Date: Mon, 5 Jan 2026 08:04:23 -0800
The changes aim at adding additional tracepoints variables to help
debuggers attribute them to specific processes.
The PID field uses in_task() to reliably detect when we're in process
context and can safely access current->pid. When not in process context
(such as in interrupt or in an asynchronous RCU context), the field is set
to -1 as a sentinel value.
