[PATCH 9/14] DebugFS : file/directory creation error handling

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


From: Mathieu Desnoyers <[email protected]>

Fix error handling of file and directory creation in DebugFS.

The error path should release the file system because no _remove will be called
for this erroneous creation.
