Subject: [PATCH] blscfg: Don't attempt to sort by version if not present in
|
|
all BLS files
|
|
|
|
Commit a16805341cc ("blscfg: sort BLS entries by 'version' field") made to
|
|
sort by the version field take precedence over the BLS fragment file name.
|
|
|
|
But it also uses the lack of the version field in one BLS fragment as sort
|
|
criterion, which means that entries could be wrongly sorted if one of them
|
|
doesn't have a version field and others do.
|
|
|
|
So only sort by version if all the BLS entries have this field defined,
|
|
otherwise just fallback to sorting by the BLS file name.
