Bug in mm/thrash.c function grab_swap_token()
Following bug was uncovered by compiling with '-W' flag:
CC mm/thrash.o
mm/thrash.c: In function âgrab_swap_tokenâ:
mm/thrash.c:52: warning: comparison of unsigned expression < 0 is always false
Variable token_priority is unsigned, so decrementing first and then
checking the result does not work; fixed by reversing the test, patch
attached (compile tested only).
I am not sure if likely() makes much sense in this new situation, but
I'll let somebody else to make a decision on that.
