pmem: fix a name collision
Kernel test robot detected name collision when compiled on 'um' architecture. Rename "to_phys()" to "pmem_to_phys()". >> drivers/nvdimm/pmem.c:48:20: error: conflicting types for 'to_phys'; have 'phys_addr_t(struct pmem_device *, phys_addr_t)' {aka 'long long unsigned int(struct pmem_device *, long long unsigned int)'} 48 | static phys_addr_t to_phys(struct pmem_device *pmem, phys_addr_t offset) | ^~~~~~~ In file included from arch/um/include/asm/page.h:98, from arch/um/include/asm/thread_info.h:15, from include/linux/thread_info.h:60, from include/asm-generic/preempt.h:5, from ./arch/um/include/generated/asm/preempt.h:1, arch/um/include/shared/mem.h:12:29: note: previous definition of 'to_phys' with type 'long unsigned int(void *)' 12 | static inline unsigned long to_phys(void *virt) | ^~~~~~~ vim +48 drivers/nvdimm/pmem.c 47 > 48 static phys_addr_t to_phys(struct pmem_device *pmem, phys_addr_t offset) 49 { 50 return pmem->phys_addr + offset; 51 } 52 Fixes: 9409c9b6709e (pmem: refactor pmem_clear_poison()) Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Jane Chu <jane.chu@oracle.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Link: https://lore.kernel.org/r/20220630182802.3250449-1-jane.chu@oracle.com Signed-off-by: Dan Williams <dan.j.williams@intel.com>
