Hi,

Please ignore the last email. I sent it to the wrong list.
This is a rhel6 patch, not meant for the development kernel tree.

> 
> Before this patch function gfs2_write_calc_reserv built in several
> "slop" blocks into its calculations for the number of blocks required
> to do a write. This was fine for the most part, but when the file
> system is down to its last blocks, and needs to be extended with
> gfs2_grow, the rindex file needs to use a minimum amount of blocks.
> This patch makes a special exception for the rindex file, which
> now calculates a bare minimum number of blocks we need to allocate.
