From 68d1498c3a7e5223b587ad067111fbed12df52a1 Mon Sep 17 00:00:00 2001 From: Russell Cattelan Date: Fri, 6 May 2005 06:42:22 -0700 Subject: [PATCH] [XFS] Fix a bug in xfs_iomap for extent handling of write cases This may be the cause of several open PV's of incorrect delay flags being set and then tripping asserts. Do not return a delay alloc extent when the caller is asking to do a write.
