gssd: Error out when rpc_pipefs directory is empty
|
|
|
64c563 |
|
|
|
64c563 |
When there is no kernel modules loaded the rpc_pipefs
|
|
|
64c563 |
directory is empty, which cause rpc.gssd to silently
|
|
|
64c563 |
exit.
|

|
|
|

This patch adds a check to see if the topdirs_list
|
|
|
64c563 |
is empty. If so error out without dropping a core.
