Hi Mulyadi,
The file mm-flags.h defines a set of macros like
#define TESTPAGEFLAG(uname, lname) \
static inline int Page##uname(struct page *page) \
{ return test_bit(PG_##lname, &page->flags); }
This macro creates the function you are lookign for. PG_swapbacked is the
bit for marking if page is backed by swap. I believe ##uname of swapbacked
is equivalent to SwapBacked and similarly lname is swapbacked itself.
