The patch titled md: reinitialise more mddev fields in do_md_stop. has been removed from the -mm tree. Its filename was md-reinitialise-more-mddev-fields-in-do_md_stop.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: md: reinitialise more mddev fields in do_md_stop. From: NeilBrown <neilb@xxxxxxx> I keep finding problems where an mddev gets reused and some fields has a value from a previous usage that confuses the new usage. So clear all fields that could possible need clearing when calling do_md_stop. Also initialise the 'level' of a new array to LEVEL_NONE (which isn't 0).
