Subject: [PATCH] um: tlb: Remove unused flush_tlb_mm_range function
Date: Sun, 14 Apr 2024 22:19:34 +0100 [thread overview]
Message-ID: <20240414211934.393303-1-ivan.orlov0322@gmail.com> (raw)
GCC 11.4.0 produces the following warning when compiling the kernel for
UML architecture (with UML defconfig):
arch/um/kernel/tlb.c:579:6: warning: no previous prototype for ‘flush_tlb_mm_range’ [-Wmissing-prototypes]
579 | void flush_tlb_mm_range(struct mm_struct *mm, unsigned long start,)
This function is not used anywhere. It is not exported with
`EXPORT_SYMBOL` either, and therefore it is not usable for dynamically
loaded modules. Remove this function.
