Subject: [PATCH 16/30] Fix "irq -a" option on Linux 6.0 and later
|
|
|
|
Kernel commit f0dd891dd5a1d ("lib/cpumask: move some one-line wrappers
|
|
to header file"), which is contained in Linux 6.0 and later kernels,
|
|
inlined alloc_cpumask_var() function. As a result, the "irq -a" option
|
|
fails to determine that cpumask_var_t is a pointer, and displays wrong
|
|
CPU affinity for IRQs:
|
|
|
|
crash> irq -a
|
|
IRQ NAME AFFINITY
|
|
1 i8042 3
|
|
4 ttyS0
|
|
8 rtc0
|
|
9 acpi 3
|
|
12 i8042 3
|
|
...
|
|
|
|
Use alloc_cpumask_var_node() function symbol instead to fix it.
