Unless you patched it yourself, I don't know of any kernels that include
this patch by default.  Finally with 2.5 here, it will go into the main

If you need to resize your filesystem, you need to unmount it (go into
single user mode from a console window (not X!) with "telinit 1", which
will stop most of the programs running on the system).  Then run
"ext2resize /dev/vg1/vol_usr" which will detect the size of the LV and
resize the filesystem to fill it.
