Thank you. I'll push that soon, with this correction: diff --git a/NEWS b/NEWS index 7797e4f..5d8df35 100644 --- a/NEWS +++ b/NEWS @@ -39,7 +39,7 @@ GNU parted NEWS -*- outline -*- ->block_size values. parted now uses ext_range device sysfs attribute to determine maximum number - of partitions the device can hold.

With this change, parted now correctly informs kernel about new partitions on partitionable MD RAID devices. ** Changes in behavior -- 1.7.8.rc3.31.g017d1 Oh, and I've removed your Signed-off-by: lines. They are needless clutter when you're the author. If you have that enabled globally, please turn it off for parted, e.g., by running this in your clone(s): git config format.signoff false
