This still looks like the same annotation problem in
generic_file_splice_write() I already sent a patch for.

Fix now pushed to overlayfs.v22/overlayfs.current.

Also added ops to shmem to support the cases where RENAME_EXCHANGE and
RENAME_WHITEOUT are needed.  Not sure if the testsuite goes into these
at all, but anyway.

If I remove the assert_early_copy_up calls from impermissible.test
(which seem to be bogus), then the suite passes for overlayfs without
lockdep problems for me.

Thanks,
Miklos
