From 6743099ce57a40509a86849a22317ed4b7516911 Mon Sep 17 00:00:00 2001 From: Arkadiusz Mi?kiewicz Date: Sun, 26 Sep 2010 06:10:18 +0000 Subject: xfs: Extend project quotas to support 32bit project ids MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch adds support for 32bit project quota identifiers. On disk format is backward compatible with 16bit projid numbers. projid on disk is now kept in two 16bit values - di_projid_lo (which holds the same position as old 16bit projid value) and new di_projid_hi (takes existing padding) and converts from/to 32bit value on the fly. xfs_admin (for existing fs), mkfs.xfs (for new fs) needs to be used to enable PROJID32BIT support.
