Subject: Fix the used device size in mdadm -D output.
X-Git-Tag: mdadm-2.6.9~6
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a1236192111a8425e6c6d81c44103e9f4a2f465c;p=thirdparty%2Fmdadm.git

Fix the used device size in mdadm -D output.

As get_component_size() returns the number of used sectors of a device
we need halve before pringing as K, and shift the value by 9, not 10,
before passing to human_size.

Thanks to Andre Noll <maan@systemlinux.org> for identifying problem
(and a slightly different version of this patch)
