+Subject: ext4: avoid kmemcheck complaint from reading uninitialized memory
+
+From: Theodore Ts'o <tytso@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).
