3.2-stable review patch. If anyone has any objections, please let me know.
------------------ From: Theodore Ts'o <ty...@mit.edu> commit 7e731bc9a12339f344cddf82166b82633d99dd86 upstream. Commit 03179fe923 introduced a kmemcheck complaint in ext4_da_get_block_prep() because we save and restore ei->i_da_metadata_calc_last_lblock even though it is left uninitialized in the case where i_da_metadata_calc_len is zero. This doesn't hurt anything, but silencing the kmemcheck complaint makes it easier for people to find real bugs. Addresses https://bugzilla.kernel.org/show_bug.cgi?id=45631 (which is marked as a regression).
