[PATCH 09/13] staging: lustre: remove ldebugfs_obd_seq_create() wrapper function

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

 



It was just calling debugfs_create_file() so unwind things and just call
the real function instead.  This ends up saving a number of lines as
there was never any error handling happening anyway, so that all can be
removed as well.
