[PATCH 22/25] libxfs: remove the libxfs_{get,put}bufr APIs

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

 



From: Darrick J. Wong <darrick.wong@xxxxxxxxxx>

Hide libxfs_getbufr since nobody should be using the internal function,
and fold libxfs_putbufr into its only caller.
