Subject: mm/memprofiling: explicitly include irqflags.h in alloc_tag.h
Date: Sun, 7 Apr 2024 15:32:52 +0200
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.
