Subject: linux-kernel-header: O_NOATIME needed for lvm

Package: linux-kernel-headers
Version: 2.5.999-test7-bk-17
Severity: critical
File: linux-kernel-header
Justification: breaks the whole system

Hi,

when one tries to run pvmove or lvsnapshot on / the lvm will deadlock
itself due to atime updates on /dev/ being blocked while the LVM is
locked. Sine any read/write access to / will be blocked the system
breaks.

To prevent this lvm uses O_NOATIME where available, which is still not
the case in current linux-kernel-headers.

On closing this bug please reassign it to lvm instead because it
needs to Build-Depend on new enough headers and recompile.

MfG
	Goswin
