Subject: feat: Let --inspect retain atime if possible
X-Git-Tag: v4.10~116
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1c922349d736cdb47669b2388f1bbb806f1b5290;p=thirdparty%2Fccache.git

feat: Let --inspect retain atime if possible

For storage that relies on atime for LRU cleanup purposes, it makes
sense not to affect atime when inspecting cache entries.
