Subject: [PATCH 06/18] xfs: use a per-resource struct for incore dquot data
Date: Tue, 30 Jun 2020 08:42:29 -0700
Message-ID: <159353174945.2864738.16786596402939892293.stgit@magnolia> (raw)
In-Reply-To: <159353170983.2864738.16885438169173786208.stgit@magnolia>

From: Darrick J. Wong <darrick.wong@oracle.com>

Introduce a new struct xfs_dquot_res that we'll use to track all the
incore data for a particular resource type (block, inode, rt block).
This will help us (once we've eliminated q_core) to declutter quota
functions that currently open-code field access or pass around fields
around explicitly.
