Change subject: KUDU-613: Introduce SLRU cache
......................................................................


Patch Set 10:

(4 comments)

Just glanced over the tests, and there is one question I'd like to clarify 
before going over the rest of the code.

http://gerrit.cloudera.org:8080/#/c/20607/10/src/kudu/util/slru_cache-test.cc
File src/kudu/util/slru_cache-test.cc:

http://gerrit.cloudera.org:8080/#/c/20607/10/src/kudu/util/slru_cache-test.cc@76
PS10, Line 76:
nit: the indent should be 2 + 4 = 6 spaces here


http://gerrit.cloudera.org:8080/#/c/20607/10/src/kudu/util/slru_cache-test.cc@80
PS10, Line 80:      { }
nit: wrong indent


http://gerrit.cloudera.org:8080/#/c/20607/10/src/kudu/util/slru_cache-test.cc@209
PS10, Line 209:   RETURN_IF_NO_NVM_CACHE(GetParam().first);
Here and below: does it mean the test is run only on NVM cache?  If so, how to 
test SLRU cache on DRAM then?

And why running/skipping SLRU-related tests is predicated in NVM cache presence 
at all?

PS10, Line 244: Erase
Does it make sense to test the erase operation for both the cases when an entry 
is in probationary and protected segments?
