      raw: use explicit llseek file operations · cb3b9cf8
      由 Arnd Bergmann 提交于 
      The raw_fops may need to seek, so there should
be an explicit reference to default_llseek.
raw_ctl_fops does not contain a read or write
method, so we use noop_llseek to ignore seeking
requests without an error.

      ibmasmfs: use generic_file_llseek · 275bd41a
      由 Arnd Bergmann 提交于 
      The default for llseek will change to no_llseek,
so ibmasmfs needs to add explicit .llseek
assignments. Since we're dealing with regular
files from a VFS perspective, use generic_file_llseek.

      spufs: use llseek in all file operations · fe3b79df
      由 Arnd Bergmann 提交于 
      The default for llseek is changing, so we need
explicit operations everywhere.

      arm/omap: use generic_file_llseek in iommu_debug · c0b0aca0
      由 Arnd Bergmann 提交于 
      In future kernels, debugfs files need to specify
the llseek operation explicitly to allow seeking.
This sets the llseek operation in the omap iommu
debugfs files to generic_file_llseek, which is
appropriate for files using simple_read_from_buffer.

      lkdtm: use generic_file_llseek in debugfs · 05271ec4
      由 Arnd Bergmann 提交于 
      When the default llseek behavior gets changed to
not allowing seek, all file operations that rely
on the current behaviour need to use an explicit
.llseek operation.

The files that lkdtm uses in debugfs are regular
files and they get read using simple_read_from_buffer,
so generic_file_llseek is the right operation.

      net/wireless: use generic_file_llseek in debugfs · 2b18ab36
      由 Arnd Bergmann 提交于 
      The default llseek operation is changing from
default_llseek to no_llseek, so all code relying on
the current behaviour needs to make that explicit.

The wireless driver infrastructure and some of the drivers
make use of generated debugfs files, so they cannot
be converted by our script that automatically determines
the right operation.

All these files use debugfs and they typically rely
on simple_read_from_buffer, so the best llseek operation
here is generic_file_llseek.

      drm: use noop_llseek · dc880abe
      由 Arnd Bergmann 提交于 
      The drm device drivers currently allow seeking on the
character device but never care about the actual
file position.

When we change the default llseek operation to be
no_llseek, calling llseek on a drm device would
return an error condition, which is an API change.

Explicitly setting noop_llseek lets us keep the
current API.
