Additional Information

S3fs has a ensure_diskfree option, but if filesystems vary by size, ensure_diskfree would have to be dynamic to each system running s3fs.

Wouldn't it be easier to have a cache_limit option that prevents the default (tmp) or cachedir from exceeding that value? This would allow users to set X value for cache size to any cachedir they chose without the need for calculating how much free space should reside in tmp or cachedir per system.

Version of s3fs being used (s3fs --version)

s3fs-fuse-1.85-1.el7.x86_64

Version of fuse being used (pkg-config --modversion fuse, rpm -qi fuse, dpkg -s fuse)
