[PATCH] mm/memprofiling: explicitly include irqflags.h in alloc_tag.h

From: Klara Modin
Date: Sun Apr 07 2024 - 09:43:24 EST


linux/alloc_tag.h uses the macro this_cpu_inc which eventually expands to:

#define this_cpu_generic_to_op(pcp, val, op) \
do { \
unsigned long __flags; \
raw_local_irq_save(__flags); \
raw_cpu_generic_to_op(pcp, val, op); \
raw_local_irq_restore(__flags); \
} while (0)

The macros raw_local_irq_save and raw_local_irq_restore are defined in
linux/irqflags.h which is not included implicitly on all configs.
Therefore, include it explicitly.
