Subject: mdadm/grow: correct the s->size > 1 to make 'max' work
X-Git-Tag: mdadm-4.1-rc1~44
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=56e1e6ace095893b361f26e750eee58fe3068340;p=thirdparty%2Fmdadm.git

mdadm/grow: correct the s->size > 1 to make 'max' work

s->size > 1 : s->size is '1' when '--grow --size max'
parameter is specified, so correct this test here.

Fixes: 1b21c449e6f2 ("mdadm/grow: adding a test to ensure resize was required")
