Hi Linus, it looks like you haven't pulled from the ext4 tree yet.

FYI, I've since added three more patches to the for_linus branch to fix a few more bugs:

Theodore Ts'o (3):
jbd2: Export jbd2_log_start_commit to fix ext4 build
ext4: Do not override ext2 or ext3 if built they are built as modules
ext4: Fix potential fiemap deadlock (mmap_sem vs. i_data_sem)
