Re: [PATCH v9 09/13] exfat: add misc operations

[Valdis KlÄtnieks]

When compiling on a 32-bit system like Raspian on an RPi4, the compile dies:

  CC [M]  fs/exfat/misc.o
fs/exfat/misc.c: In function 'exfat_time_unix2fat':
fs/exfat/misc.c:157:16: error: 'UNIX_SECS_2108' undeclared (first use in this function); did you mean 'UNIX_SECS_1980'?
  if (second >= UNIX_SECS_2108) {
                ^~~~~~~~~~~~~~
                UNIX_SECS_1980
fs/exfat/misc.c:157:16: note: each undeclared identifier is reported only once for each function it appears in
make[2]: *** [scripts/Makefile.build:266: fs/exfat/misc.o] Error 1

The problem is that the definition of UNIX_SECS_2108  is wrapped:

+#if BITS_PER_LONG == 64
+#define UNIX_SECS_2108    4354819200L
+#endif

but the usage isn't.
