[PATCH] remove unlikely(sb) in prune_dcache
likely profiling shows that the following is a miss.
After boot:
[+- ] Type | # True | # False | Function:Filename@Line
+unlikely | 1074| 0 prune_dcache()@:fs/dcache.c@409
After a bonnie++ run:
+unlikely | 66716| 19584 prune_dcache()@:fs/dcache.c@409
So remove it.
