Merge tag 'befs-v4.9-rc1' of git://github.com/luisbg/linux-befs
Pull befs fixes from Luis de Bethencourt: "I recently took maintainership of the befs file system [0]. This is the first time I send you a git pull request, so please let me know if all the below is OK. Salah Triki and myself have been cleaning the code and fixing a few small bugs. Sorry I couldn't send this sooner in the merge window, I was waiting to have my GPG key signed by kernel members at ELCE in Berlin a few days ago."
