Hi, With kernel 2.4.10, when I do $ mkdir foo; cd foo; rmdir ../foo; ls then ls becomes zombie. $ ps xau|grep ls liu 596 0.0 0.0 148 88 ? D 12:03 0:00 ls This does not happen with 2.4.10 on an ext2 filesystem, nor with 2.4.9/ext3. The command cd instead of ls is OK. Distribution is Slackware 8.0 and the kernels are stock ones. Liu

George has release acked all of these. Otherwise mostly minor updates this time around. Summary: A == acked, M == modified A xen: arm64: Add 8250 earlyprintk support A xen: arm64: Add Basic Platform support for APM X-Gene Storm. A xen: arm64: Add APM implementor id to processor implementers. M xen: arm: add a quirk to handle platforms with unusual GIC layout A xen: arm: allow platform

I''m afraid this series is rather a grab bag and it is distressingly large at this stage. With this series I can boot an Xgene board until it fails to find its SATA controller. This is a dom0 issue for which patches are pending from APM (/me nudges Anup). As well as the APM specific platform stuff there are also some generic improvements which were either necessary or useful during this

First off, Apologies for the massive patch series... This series boots a 32-bit dom0 kernel to a command prompt on an ARMv8 (AArch64) model. The kernel is the same one as I am currently using with the 32 bit hypervisor I haven''t yet tried starting a guest or anything super advanced like that ;-). Also there is not real support for 64-bit domains at all, although in one or two places I

This round implements all of the review comments from V2 and all patches are now acked. Unless there are any objections I intend to apply later this morning. Ian.
