[PATCH 1/2] xfs: don't pass iomap flags to xfs_reflink_allocate_cow

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

 



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

Don't pass raw iomap flags to xfs_reflink_allocate_cow; signal our
intention with a boolean argument.
