Re: [PATCH parted 1/5] libparted: add ped_device_get_xxx_aligment() functions

[Hans de Goede <hdegoede@xxxxxxxxxx>]

Hi,

Note, these patches may apply to master with a couple of lines offset
left and right, as I also have some patches in my local tree to update
parted to keep working with upcoming lvm2 (libdevmapper) changes, I'm still
waiting on testing feedback for these (the libdevmapper) patches before
submitting them.

Regards,

Hans

p.s.

I also plan to backport this set of 5 to libparted-1.9 and add them to the
Fedora packages for F-13.
