Re: [squid-users] Question on aufs

Hi Marc,

The storeAufsOpenDone keep appearing in cache log... not sure if it's a
time bomb waiting to fail :(

Notice that the aufs source files (src/fs/aufs) are quite some time ago,
and there are some changes in 2.5.

Do you think is a good idea to patch the aufs with the 2.5 source?
If so, what are the files I should patch?

Thanks,
Wei Keong
