shodanshok 1d2b0563f7 Fix ARC target collapse when zfs_arc_meta_limit_percent=100 ... Reclaim metadata when arc_available_memory < 0 even if meta_used is not bigger than arc_meta_limit. As described in https://github.com/openzfs/zfs/issues/14054 if zfs_arc_meta_limit_percent=100 then ARC target can collapse to arc_min due to arc_purge not freeing any metadata. This patch lets arc_prune to do its work when arc_available_memory is negative even if meta_used is not bigger than arc_meta_limit, avoiding ARC target collapse.
