Subject: kernel/fork: update obsolete use_mm references to kthread_use_mm
Date: Wed, 7 Jan 2026 08:15:32 +0000

The comment for get_task_mm() in kernel/fork.c incorrectly references the
deprecated function `use_mm()`, which has been renamed to
`kthread_use_mm()` in kernel/kthread.c.

This patch updates the documentation to reflect the current function
names, ensuring accuracy when developers refer to the kernel thread memory
context API.

No functional changes were introduced.
