Tejun Heo a1ed5b0cff klist: don't iterate over deleted entries ... A klist entry is kept on the list till all its current iterations are finished; however, a new iteration after deletion also iterates over deleted entries as long as their reference count stays above zero. This causes problems for cases where there are users which iterate over the list while synchronized against list manipulations and natuarally expect already deleted entries to not show up during iteration. This patch implements dead flag which gets set on deletion so that iteration can skip already deleted entries. The dead flag piggy backs on the lowest bit of knode->n_klist and only visible to klist implementation proper. While at it, drop klist_iter->i_head as it's redundant and doesn't offer anything in semantics or performance wise as klist_iter->i_klist is dereferenced on every iteration anyway.
