From de69e5f44ecbf1d9faca4f473f4210473d26cd41 Mon Sep 17 00:00:00 2001 From: Nathan Scott Date: Thu, 3 Nov 2005 13:53:34 +1100 Subject: [XFS] Add a mechanism for XFS to use the generic quota sync method. This is now used to issue a delayed allocation flush before reporting quota, which allows the used space quota report to match reality.
