All sorts of stuff, from more people than usual. Among other stuff:
* sanitizing superblock methods (me, hch, Jan Kara)
* more pushing of lock_super() and BKL down into fs (by now only ->get_sb()
has the latter held by caller and nothing in VFS touches the former) (me,
hch, Alessio Igor Bogani)
* ->fsync() sanitizing and fixes (tangentially related to sb methods work;
file_fsync() must die and it's getting on the way to extinction)
* _very_ welcome speedup of mnt_want_write() from Nick Piggin
* solution for Trond's "nfs wants to have pathname resolution starting
at isolate vfsmount, with automounting" problem
