include/linux/mm.h: provide consistent declaration for num_poisoned_pages
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.
