[PATCH 4/4] xfs: Make inode32 a remountable option

To: xfs@xxxxxxxxxxx
Subject: [PATCH 4/4] xfs: Make inode32 a remountable option
From: Carlos Maiolino <cmaiolino@xxxxxxxxxx>

In-reply-to: <1347641381-30050-1-git-send-email-cmaiolino@xxxxxxxxxx>
References: <1347641381-30050-1-git-send-email-cmaiolino@xxxxxxxxxx>
As inode64 is the default option now, and was also made remountable previously,
inode32 can also be remounted on-the-fly when it is needed.
