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. Signed-off-by: Benjamin Marzinski <bmarzins@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
