From 0b04dd5d7ca79ccb88e258641b328fe4f548272a Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Wed, 15 Jul 2020 17:51:47 -0700 Subject: [PATCH] xfs: always use xfs_dquot_type when extracting type from a dquot Always use the xfs_dquot_type helper to extract the quota type from an incore dquot. This moves responsibility for filtering internal state information and whatnot to anybody passing around a struct xfs_dquot. Signed-off-by: Darrick J.
