Subject: [PATCH 13/15] llseek: automatically add .llseek fop
All file_operations should get a .llseek
operation so we can make nonseekable_open
the default for future file operations
without a .llseek pointer.
The three cases that we can automatically
detect are no_llseek, seq_lseek and
default_llseek. For cases where we can
we can automatically prove that the
file offset is always ignored, we use
noop_llseek, which maintains the current
behavior of not returning an error from
a seek.
New drivers should normally not use
noop_llseek but instead use no_llseek and
call nonseekable_open at open time.
Existing drivers can be converted to do
the same when the maintainer knows for
certain that no user code relies on calling
seek on the device file.
The generated code is often incorrectly
indented and right now contains comments that
clarify for each added line why a specific
variant was chosen. In the version that gets
submitted upstream, the comments will be gone
and I will manually fix the indentation,
because there does not seem to be a way to
do that using coccinelle.
Some amount of new code is currently sitting
in linux-next that should get the same
modifications, which I will do at the end of
the merge window.
Many thanks to Julia Lawall for helping me
learn to write a semantic patch that does
all this.

// This adds an llseek= method to all file operations,
// as a preparation for making no_llseek the default.
//
// The rules are
// - use no_llseek explicitly if we do nonseekable_open
// - use seq_lseek for sequential files
// - use default_llseek if we know we access f_pos
// - use noop_llseek if we know we don't access f_pos,
// but we still want to allow users to call lseek
