[PATCH 5.10 037/452] rcu: Make TASKS_RUDE_RCU select IRQ_WORK
From: Greg Kroah-Hartman

[ Upstream commit 46e861be589881e0905b9ade3d8439883858721c ]
The TASKS_RUDE_RCU does not select IRQ_WORK, which can result in build
failures for kernels that do not otherwise select IRQ_WORK. This commit
therefore causes the TASKS_RUDE_RCU Kconfig option to select IRQ_WORK.

This option enables a task-based RCU implementation that uses
only context switch (including preemption) and user-mode
