Subject: [PATCH] libmultipath: check if adopt_path() really added current path
|
|
|
|
The description of 2d32d6f ("libmultipath: adopt_paths(): don't bail out on
|
|
single path failure") said "we need to check after successful call to
|
|
adopt_paths() if that specific path had been actually added, and fail in the
|
|
caller otherwise". But the commit failed to actually implement this check.
|
|
Instead, it just checked if the path was member of the pathvec, which will
|
|
almost always be the case.
|
|
|
|
Fix it by checking what actually needs to be checked, membership of the
|
|
path to be added in mpp->paths.
|
|
|
|
Fixes: 2d32d6f ("libmultipath: adopt_paths(): don't bail out on single path failure")
