From 6d89332b776fc11bac0073209e44ec8f39831e4e Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Thu, 2 Feb 2006 14:28:03 -0800 Subject: [PATCH] [PATCH] md: Fix device-size updates in md As 'array_size' is a 'sector_t', it may overflow inappropriately when shifted 10 bits. So We should cast it to a loff_t first. There are two places with this problem, but the second (in update_raid_disks) isn't needed so just remove it: The only personality that handles ->reshape currently is raid1, and it doesn't change the size of the array. When added for raid5/6, reshape again won't change the size of the array, at least not straight away. This code might be need for reshaping 'linear' but linear->shape, if implemented, should probably do the i_size_write itself.
