      ... and the same for reiserfs.  The difference here is that we need
      insert_inode_locked4() to match iget5_locked().

      nfsd race fixes: ext2 · 41080b5a
      Al Viro authored
      * make ext2_new_inode() put the inode into icache in locked state
      * do not unlock until the inode is fully set up; otherwise nfsd
      might pick it in half-baked state.
      * make sure that ext2_new_inode() does *not* lead to two inodes with the
      same inumber hashed at the same time; otherwise a bogus fhandle coming
      from nfsd might race with inode creation:
      
      nfsd: iget_locked() creates inode
      nfsd: try to read from disk, block on that.
      ext2_new_inode(): allocate inode with that inumber
      ext2_new_inode(): insert it into icache, set it up and dirty
      ext2_write_inode(): get the relevant part of inode table in cache,
      set the entry for our inode (and start writing to disk)
      nfsd: get CPU again, look into inode table, see nice and sane on-disk
      inode, set the in-core inode from it
      
      oops - we have two in-core inodes with the same inumber live in icache,
      both used for IO.  Welcome to fs corruption...
