walkdir is used indirectly in the abort handler of SharedFileSetOnDetach, which has the following comment:
| * Callback function that will be invoked when this backend detaches from a |
|
| * DSM segment holding a SharedFileSet that it has created or attached to. If |
|
| * we are the last to detach, then try to remove the directories and |
|
| * everything in them. We can't raise an error on failures, because this runs |
|
| * in error cleanup paths. |

walkdir itself has elevel, which is set to LOG in that case, so it should ot throw an ERROR.
The fix seems simple enough: AllocateDir and reserveAllocatedDesc should take an elevel argument and honor that. To not change the signature of AllocateDir and possibly break extions, it could simply become a wrapper of a new function like AllocateDirWithElevel(dirname, ERROR).
