[PATCH] lightnvm: pblk: fix changing GC group list for a line

[Rakesh Pandit]

pblk_line_gc_list seems to had a bug since the introduction of pblk in
getting GC list for a line.  In b20ba1bc7 while redesigning GC
algorithm it was not fixed correctly.  The problem is that even if
valid sector count (vsc) is less that mid_thrs (threshold for GC mid
list) it would always satisfy 'vsc < high_thrs' as high_thrs >
mid_thrs always.
