ceph: perform lazy reads when file mode and caps permit
If the file mode is marked as "lazy," perform cached/buffered reads when the caps permit it. Adjust the rdcache_gen and invalidation logic accordingly so that we manage our cache based on the FILE_CACHE -or- FILE_LAZYIO cap bits. Signed-off-by: Sage Weil <sage@newdream.net>
