GFS2: Improve statfs and quota usability
GFS2 now has three new mount options, statfs_quantum, quota_quantum and
statfs_percent. statfs_quantum and quota_quantum simply allow you to
set the tunables of the same name. Setting setting statfs_quantum to 0
will also turn on the statfs_slow tunable. statfs_percent accepts an
integer between 0 and 100. Numbers between 1 and 100 will cause GFS2 to
do any early sync when the local number of blocks free changes by at
least statfs_percent from the totoal number of blocks free. Setting
statfs_percent to 0 disables this.
