Log message:
Bugzilla 231904:
Port RHEL4 fast statfs (for commands such as "df") implementation over.
The "lvb" enhancement will be followed around RHEL 5.2 time frame.
Ballpark performance numbers:
dhcp145 (1 cpu HP): old df took 0.875 seconds, new df 0.008 second
dhcp146 (4 cpus DELL): old df took 0.808 seconds, new df 0.006 second.
Activated via "gfs_tool settune <mount point> statfs_fast 1" command.

Log message:
Bugzilla 220622: backport GFS2 statfs() implementation to GFS1.
There are few compromises made while porting GFS2 approach over, mostly
to avoid on-disk structure changes. GFS2 allocates (number-of-nodes + 1)
physical files into disk during mkfs time but GFS1 only has one extra
space (the unused license file) for this purpose. We deviate from GFS2
by writing the local per-node changes into a memory buffer.
Doing a "df" on a quiet filesystem now results:
dhcp145 (1 cpu HP): old df took 0.875 seconds, new df 0.008 second
dhcp146 (4 cpus DELL): old df took 0.808 seconds, new df 0.006 second.
