Hi, Jan Capek writes > It is the second of the two patches contributed by Leonid Ananiev. I've sent one but not two patches according to "ext3: Fix missed mutex unlock". Here is my patch: http://marc.theaimsgroup.com/?l=linux-kernel&m=114469290908779&w=2 --- fs/ext3/resize.c 2006-04-06 01:08:28.367109040 -0700 +++ fs/ext3/resize.c 2006-04-06 01:10:37.289509856 -0700 @@ -974,6 +974,7 @@ int ext3_group_extend(struct super_block if (o_blocks_count != le32_to_cpu(es->s_blocks_count)) { ext3_warning(sb, __FUNCTION__, "multiple resizers run on filesystem!"); + unlock_super(sb); err = -EBUSY; goto exit_put; } This patch was applied to line 974 only but not to line 767 as described in attached mail.

This one incorrectly adds the super block unlocking in the error path, though. As we can see in the function ext3_group_add() the unlock is already handled at the label 'exit_journal' for all error paths. Below is the patch that should be unrolled.
