Subject: [PATCH] libmultipath: make vector_foreach_slot_backwards work as
|
|
expected
|
|
|
|
All of the code that uses vector_foreach_slot_backwards() treats "i" as
|
|
the index of the entry "p", but the way it was coded, that wasn't the
|
|
case. "i" was the number of the entry counting from 1, not 0.
