When building bcache as a module, the following errors are silenced
by this patch:
ERROR: "call_rwsem_down_read_failed" [block/bcache.ko] undefined!
ERROR: "call_rwsem_wake" [block/bcache.ko] undefined!
There may be implications of the extra code introduced by this, but
I am not familiar with these functions. Though I can confirm that
the resulting build seems to work.
