From 3a69c7dc6f3d58aeb9ce5051fc7060d55e05c003 Mon Sep 17 00:00:00 2001 From: Yingping Lu Date: Wed, 1 Feb 2006 12:14:34 +1100 Subject: [XFS] Interim solution for attribute insertion failure during file creation due to ENOSPC. The current solution removes the inode when the attribute insertion fails. Long term solution would be to make the inode creation and attribute insertion atomic.
