Subject: Correctly initialise backup_point when reshaping backwards.
X-Git-Tag: mdadm-3.2~64
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=25da62d9adc9009a7f9d1234b784efac3c4ac24c;p=thirdparty%2Fmdadm.git

Correctly initialise backup_point when reshaping backwards.

When reshaping backwards we only backup from backup_blocks to
the start, so initialise backup_point appropriately.
