Subject: [PATCH] ovl: rename is_merge to is_lowest
|
||
|
|
|
||
|
|
The 'is_merge' is an historical naming from when only a single lower layer
|
||
|
|
could exist. With the introduction of multiple lower layers the meaning of
|
||
|
|
this flag was changed to mean only the "lowest layer" (while all lower
|
||
|
|
layers were being merged).
|
||
|
|
|
||
|
|
So now 'is_merge' is inaccurate and hence renaming to 'is_lowest'
