Subject: Create: add error checking for 'write_init_super'.
X-Git-Tag: mdadm-3.2.2~74
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ab80e597bae3df0209135a4130c93f57d5eb3e34;p=thirdparty%2Fmdadm.git

Create: add error checking for 'write_init_super'.

If this fails, we really must fail the whole 'create'.
