From 44b998e1eb254edc87177819ee693690fac68b7f Mon Sep 17 00:00:00 2001 From: David Woodhouse Date: Mon, 23 Apr 2007 12:11:46 +0100 Subject: [JFFS2] Improve failure mode if inode checking leaves unchecked space. We should never find the unchecked size is non-zero after we've finished checking all inodes. If it happens, used to BUG(), leaving the alloc_sem held and deadlocking. Instead, just return -ENOSPC after complaining. The GC thread will die, but read-only operation should be able to continue and the file system should be unmountable.
