Subject: fix: Don't use copy of mutex/condition in long-lived lock thread
X-Git-Tag: v4.8~85
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=034e3316eb4e3b6a4508f34bde2b1049c681542c;p=thirdparty%2Fccache.git

fix: Don't use copy of mutex/condition in long-lived lock thread

This was kind of due to a typo in
0babd33e84147e923a729ee07a3b85097ec8baa8. Since the LongLivedLockFile
class is not used yet, the bug does not affect any released code.
