X-Git-Tag: v2.6.27.16~15 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1d338dafbacdc12aab149c441e67150a5aed320d;p=pandora-kernel.git md: Allow metadata_version to be updated for externally managed metadata. commit ea43ddd8491feccf36267349748ea91b1194481e upstream. For externally managed metadata, the 'metadata_version' sysfs attribute is really just a channel for user-space programs to communicate about how the array is being managed. It can be useful for this to be changed while the array is active. Normally changes to metadata_version are not permitted while the array is active. Change that so that if the metadata is externally managed, the metadata_version can be changed to a different flavour of external management.
