Dear XFS-Developers, recently I copied a big file (>1TiB) over network into a XFS-Filesystem. During this I encountered this kernel trace from xfsdatad: Apr 11 13:31:32 phoenix kernel: [504985.202258] xfsdatad/1: page allocation failure. order:1, mode:0x4020 Apr 11 13:31:32 phoenix kernel: [504985.202268] Pid: 334, comm: xfsdatad/1 Not tainted 2.6.32-5-amd64 #1 Apr 11 13:31:32 phoenix kernel: [504985.202272] Call Trace: Apr 11 13:31:32 phoenix kernel: [504985.202275] <IRQ> [<ffffffff810ba5f2>] ?
