Subject: [PATCH RFC 10/12] userns: Convert xfs to use kuid/kgid/kprojid where appropriate
From: "Eric W. Biederman" <ebiederm@...ssion.com>
- Modify the incore inode to use kuid_t, kgid_t and kprojid_t.
- Remove xfs_get_projid and xfs_set_projid with projid being stored
in a single field they are unnecessary.
- Add dq_id (a struct kqid) to struct xfs_dquot to retain the incore
version of the quota identifiers.
- Pass struct kquid all of the way into xfs_qm_dqgetn and xfs_qm_dqread,
and move xfs_quota_type into xfs_dquot.c from xfs_quotaops.c to support
this change.
