Hi!
Noticed today that a rebuild of basically the same tree (a few commits apart)
in CI result in just 11% hit rate of ccache:
https://gitlab.com/mjt0k/qemu/-/jobs/6947445337#L5054
For me, the results look better:
https://gitlab.com/thuth/qemu/-/jobs/6918599017#L4954
while it should be near 100%. What's interesting in there is:
1) cache size is close to max cache size,
and more important,
2) cleanups performed 78
so it has to remove old entries before it finished the build.
Did you maybe switch between master and stable branches before that run? ...
I guess that could have invalidated most of the cached files since we
switched from CentOS 8 to 9 recently...?
