## Bug Description: In case of dht_discover code path, which is triggered
## when lookup done is nameless lookup, at the end of the lookup, even if
## it finds that self-heal is needed to fix-the layout it wont heal because
## healing code path is not added under nameless lookup.
## What to test: With Patch, Even in case of nameless lookup, if layout
## needs to be fixed, the it will be fixed wherever lookup is successful
## and it will not create any directory for subvols having ENOENT as it is
## nameless lookup.

## Assuming that we have two bricks, we can have two permutations of layout
## Case 1: Brick - A Brick - B
## 0 - 50 51-100
##
## Case 2: Brick - A Brick - B
## 51 - 100 0 - 50
##
## To ensure layout is assigned properly, the following tests should be
## performed.
##
## Case 1: Layout_b0_s = 0; Layout_b0_e = 50, Layout_b1_s=51,
## Layout_b1_e = 100;
##
## layout_b1_s = layout_b0_e + 1;
## layout_b0_s = layout_b1_e + 1; but b0_s is 0, so change to 101
## then compare
## Case 2: Layout_b0_s = 51, Layout_b0_e = 100, Layout_b1_s=0,
## Layout_b1_e = 51
##
## layout_b0_s = Layout_b1_e + 1;
## layout_b1_s = Layout_b0_e + 1; but b1_s is 0, so chage to 101.
