clang reports the following compile warning.
In file included from mm/vmscan.c:56: ./include/linux/swapops.h:327:22: warning: section attribute is specified on redeclared variable [-Wsection] extern atomic_long_t num_poisoned_pages __read_mostly; ^ ./include/linux/mm.h:2585:22: note: previous declaration is here extern atomic_long_t num_poisoned_pages; ^
Let's use __read_mostly everywhere.
