linux-next: manual merge of the logfs tree with Linus' tree

Hi all,

Today's linux-next merge of the logfs tree got a conflict in
fs/logfs/file.c between commit 02c24a82187d ("fs: push i_mutex and
filemap_write_and_wait down into ->fsync() handlers") from Linus' tree
and commit 39da12ef4bbe ("logfs: take write mutex lock during fsync and
sync") from the logfs tree.

I have no idea what needs to be done here. I fixed it like below to make
it build, but a better fix is needed.
