tools/testing/scatterlist: add missing defines
The cited commits replaced preemptible with pagefault_disabled and flush_kernel_dcache_page with flush_dcache_page respectively, hence need to update the corresponding defines in the test. scatterlist.c: In function ‘sg_miter_stop’: scatterlist.c:919:4: warning: implicit declaration of function ‘flush_dcache_page’ [-Wimplicit-function-declaration] flush_dcache_page(miter->page); ^~~~~~~~~~~~~~~~~ In file included from linux/scatterlist.h:8:0, from scatterlist.c:9: scatterlist.c:922:18: warning: implicit declaration of function ‘pagefault_disabled’ [-Wimplicit-function-declaration] WARN_ON_ONCE(!pagefault_disabled()); ^ linux/mm.h:23:25: note: in definition of macro ‘WARN_ON_ONCE’ int __ret_warn_on = !!(condition); \ ^~~~~~~~~ Link: https://lkml.kernel.org/r/20220118082105.1737320-1-maorg@nvidia.com Fixes: 723aca208516 ("mm/scatterlist: replace the !preemptible warning in sg_miter_stop()") Fixes: 0e84f5dbf8d6 ("scatterlist: replace flush_kernel_dcache_page with flush_dcache_page") Signed-off-by: Maor Gottlieb <maorg@nvidia.com> Tested-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Christoph Hellwig <hch@lst.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
