[PATCH 09/13] xfs: remove xfs_qm_dqread flags argument

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

 



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

Move the _qm_dqread functionality to _qm_dqensure, then remove the flags
argument from xfs_qm_dqread since the only DQALLOC users were internal
to xfs_dquot.c anyway.

Signed-off-by: Darrick J. Wong <darrick.wong@xxxxxxxxxx>
