[PATCH 02/10] xfs: make the key parameters to all btree query range functions const

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

 



From: Darrick J. Wong <djwong@xxxxxxxxxx>

Range query functions are not supposed to modify the query keys that are
being passed in, so mark them all const.
