But we forgot to initialize the file operations, with the result that LOCKT never results in a call to the filesystem's ->lock() method (if it exists). We could just add that one more initialization. But this hack of faking up a struct file with only some fields initialized seems the kind of thing that might cause more problems in the future. We should either do an open and get a real struct file, or make lock-testing an inode (not a file) method. This patch does the former. Reported-by: Marc Eshel Tested-by: Marc Eshel Signed-off-by: J.
