[PATCH 01/20] xfs: add a libxfs header file for staging new ioctls

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

 



From: Darrick J. Wong <djwong@xxxxxxxxxx>

Create a new xfs_fs_staging.h header where we can land experimental
ioctls without committing them to any stable interfaces anywhere.
