+Subject: [PATCH] btrfs-progs: convert/ext2: Remove check for
+ ext2_ext_attr_entry->e_value_block
+
+In latest e2fsprogs (1.44.0) definition of ext2_ext_attr_entry has
+removed member e_value_block, as currently ext* doesn't support it set
+anyway.
+
+So remove such check so that we can pass compile.
+
+Issue: #110
