Subject: BacklinkCache: Remove use of ProcessCacheLRU
X-Git-Tag: 1.31.0-rc.0~9045^2
X-Git-Url: http://git.cyclocoop.org//%22%22.str_replace%28%27%22%27%2C?a=commitdiff_plain;h=e6205019a484d56dade617ce26331b3ca4d12242;p=lhc%2Fweb%2Fwiklou.git

BacklinkCache: Remove use of ProcessCacheLRU

Follows-up af89b09a06 and e40a90f0bc, and general phasing out
of MapCacheLRU and ProcessCacheLRU.

Use of ProcessCacheLRU seems redundant in this case as it is
essentially just a keyed singleton.
