Kiran Kumar Modukuri 2c69b03004 cachefiles: Wait rather than BUG'ing on "Unexpected object collision" ... [ Upstream commit c2412ac45a ] If we meet a conflicting object that is marked FSCACHE_OBJECT_IS_LIVE in the active object tree, we have been emitting a BUG after logging information about it and the new object. Instead, we should wait for the CACHEFILES_OBJECT_ACTIVE flag to be cleared on the old object (or return an error). The ACTIVE flag should be cleared after it has been removed from the active object tree. A timeout of 60s is used in the wait, so we shouldn't be able to get stuck there.
