Linus Torvalds 40f06c7995 Changes to copy_file_range for 5.3 from Dave and Amir:
- Create a generic copy_file_range handler and make individual
   filesystems responsible for calling it (i.e. no more assuming that
   do_splice_direct will work or is appropriate)
 - Refactor copy_file_range and remap_range parameter checking where they
   are the same
 - Install missing copy_file_range parameter checking(!)
 - Remove suid/sgid and update mtime like any other file write
 - Change the behavior so that a copy range crossing the source file's
   eof will result in a short copy to the source file's eof instead of
   EINVAL
 - Permit filesystems to decide if they want to handle cross-superblock
   copy_file_range in their local handlers.

Pull copy_file_range updates from Darrick Wong:
 "This fixes numerous parameter checking problems and inconsistent
  behaviors in the new(ish) copy_file_range system call.

  Now the system call will actually check its range parameters
  correctly; refuse to copy into files for which the caller does not
  have sufficient privileges; update mtime and strip setuid like file
  writes are supposed to do; and allows copying up to the EOF of the
  source file instead of failing the call like we used to.

  Summary:

   - Create a generic copy_file_range handler and make individual
     filesystems responsible for calling it (i.e. no more assuming that
     do_splice_direct will work or is appropriate)

   - Refactor copy_file_range and remap_range parameter checking where
     they are the same

   - Install missing copy_file_range parameter checking(!)

   - Remove suid/sgid and update mtime like any other file write

   - Change the behavior so that a copy range crossing the source file's
     eof will result in a short copy to the source file's eof instead of
     EINVAL

   - Permit filesystems to decide if they want to handle
     cross-superblock copy_file_range in their local handlers"
