Andreas Gruenbacher 725d0e9d46 gfs2: Add per-reservation reserved block accounting ... Add a rs_reserved field to struct gfs2_blkreserv to keep track of the number of blocks reserved by this particular reservation, and a rd_reserved field to struct gfs2_rgrpd to keep track of the total number of reserved blocks in the resource group. Those blocks are exclusively reserved, as opposed to the rs_requested / rd_requested blocks which are tracked in the reservation tree (rd_rstree) and which can be stolen if necessary. When making a reservation with gfs2_inplace_reserve, rs_reserved is set to somewhere between ap->min_target and ap->target depending on the number of free blocks in the resource group. When allocating blocks with gfs2_alloc_blocks, rs_reserved is decremented accordingly. Eventually, any reserved but not consumed blocks are returned to the resource group by gfs2_inplace_release.
