ocfs2: Try to free truncate log when meeting ENOSPC in write.
Recently, one of our colleagues meet with a problem that if we write/delete a 32mb files repeatly, we will get an ENOSPC in the end. And the corresponding bug is 1288. http://oss.oracle.com/bugzilla/show_bug.cgi?id=1288 The real problem is that although we have freed the clusters, they are in truncate log and they will be summed up so that we can free them once in a whole. So this patch just try to resolve it. In case we see -ENOSPC in ocfs2_write_begin_no_lock, we will check whether the truncate log has enough clusters for our need, if yes, we will try to flush the truncate log at that point and try again. This method is inspired by Mark Fasheh <mfasheh@suse.com>. Thanks. Cc: Mark Fasheh <mfasheh@suse.com> Signed-off-by: Tao Ma <tao.ma@oracle.com> Signed-off-by: Joel Becker <joel.becker@oracle.com>
