Subject: [PATCH 179/190] Upcall: Fix an issue with invalidating parent entries
|
|
|
7f4c2a |
|
|
|
7f4c2a |
Any directory or file creation should result in cache-invalidation
|
|
|
7f4c2a |
requests sent to parent directory. However that is not the case
|
|
|
7f4c2a |
currently due to a bug while processing these requests in the
|
|
|
7f4c2a |
upcall xlator. We need to do invalidation checks on parent inode.
|
|
|
7f4c2a |
|
|
|
7f4c2a |
Fixed the same. Also fixed an issue with null client entries while
|
|
|
7f4c2a |
sending upcall notifications.
|
|
|
7f4c2a |
|
|
|
7f4c2a |
This is backport of the below upstream fix
