Re: [squid-users] propose additional field in cache_dir

Are you sure you want this?

UNIX filesystems like to have a certain percentage of the filesystem
free to be able to limit fragmentation somewhat and optimize writing of
files/directories.

Anyway, adding the requested feature to Squid-2.4 should be quite
simple. Left as an exercise to an interested reader.

Hints: See src/cf.data.pre, src/fs/*/*_dir_*.c
