Subject: md/bitmap: ensure to load bitmap when creating via sysfs.
X-Git-Tag: v3.2.14~81
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=aae19423e23df33f18e49f7558cb660aa485df90;p=pandora-kernel.git

md/bitmap: ensure to load bitmap when creating via sysfs.

commit 4474ca42e2577563a919fd3ed782e2ec55bf11a2 upstream.

When commit 69e51b449d383e (md/bitmap:  separate out loading a bitmap...)
created bitmap_load, it missed calling it after bitmap_create when a
bitmap is created through the sysfs interface.
So if a bitmap is added this way, we don't allocate memory properly
and can crash.

This is suitable for any -stable release since 2.6.35.
