      VM: add "vm_mmap()" helper function · 6be5ceb0
      Linus Torvalds 提交于
      This continues the theme started with vm_brk() and vm_munmap():
      vm_mmap() does the same thing as do_mmap(), but additionally does the
      required VM locking.
      
      This uninlines (and rewrites it to be clearer) do_mmap(), which sadly
      duplicates it in mm/mmap.c and mm/nommu.c.  But that way we don't have
      to export our internal do_mmap_pgoff() function.
      
      Some day we hopefully don't have to export do_mmap() either, if all
      modular users can become the simpler vm_mmap() instead.  We're actually
      very close to that already, with the notable exception of the (broken)
      use in i810, and a couple of stragglers in binfmt_elf.

      Like the vm_brk() function, this is the same as "do_munmap()", except it
      does the VM locking for the caller.

      simple_open: automatically convert to simple_open() · 234e3405
      Stephen Boyd 提交于
      Many users of debugfs copy the implementation of default_open() when
      they want to support a custom read/write function op.  This leads to a
      proliferation of the default_open() implementation across the entire
      tree.
      
      Now that the common implementation has been consolidated into libfs we
      can replace all the users of this function with simple_open().
      
      This replacement was done with the following semantic patch:
      
      <smpl>
      @ open @
      identifier open_f != simple_open;
      identifier i, f;
      @@
      -int open_f(struct inode *i, struct file *f)
      -{
      (
      -if (i->i_private)
      -f->private_data = i->i_private;
      |
      -f->private_data = i->i_private;
      )
      -return 0;
      -}
