[PATCH] Revert "igb: Disable threaded IRQ for igb_msix_other"
From: Wander Lairson Costa
Date: Mon Nov 04 2024 - 07:41:31 EST
This reverts commit 338c4d3902feb5be49bfda530a72c7ab860e2c9f.
Sebastian noticed the ISR indirectly acquires spin_locks, which are
sleeping locks under PREEMPT_RT, which leads to kernel splats.
