Subject: [PATCH 5/7] xfs: switch xfs_get_defquota to take explicit type
Date: Wed, 20 May 2020 21:35:16 -0500	[thread overview]
Message-ID: <1590028518-6043-6-git-send-email-sandeen@redhat.com> (raw)
In-Reply-To: <1590028518-6043-1-git-send-email-sandeen@redhat.com>

xfs_get_defquota() currently takes an xfs_dquot, and from that obtains
the type of default quota we should get (user/group/project).

But early in init, we don't have access to a fully set up quota, so
that's not possible.  The next patch needs go set up default quota
timers early, so switch xfs_get_defquota to take an explicit type
and add a helper function to obtain that type from an xfs_dquot
for the existing callers.
