From: Jérôme Glisse <jgli...@redhat.com>
This is part of patchset to remove dependency on struct page.mapping
field so that we can temporarily update it to point to a special
structure tracking temporary page state (note that original mapping
pointer is preserved and can still be accessed but at a cost).
Add struct address_space to set_page_dirty() callback arguments.
Note that this patch does not make use of the new argument, nor does
it use a valid one at call site (by default this patch just use NULL
for new argument value).
Use following script (from root of linux kernel tree):
./that-script.sh that-semantic-patch.spatch
%<--------------------------------------------------------------------
#!/bin/sh
spatch_file=$1
echo PART1 ===========================================================
# P1 find callback functions name
spatch --dir . --no-includes -D part1 --sp-file $spatch_file
echo PART2 ===========================================================
# P2 change callback function prototype
cat /tmp/unicorn-functions | sort | uniq | while read func ; do
for file in $( git grep -l $func -- '*.[ch]' ) ; do
echo $file
spatch --no-includes --in-place -D part2 \
-D fn=$func --sp-file $spatch_file $file
done
done
echo PART 3 ==========================================================
# P3 find all function which call the callback
spatch --dir . --include-headers -D part3 --sp-file $spatch_file
echo PART 4===========================================================
# P4 change all funcitons which call the callback
cat /tmp/unicorn-files | sort | uniq | while read file ; do
echo $file
spatch --no-includes --in-place -D part4 \
--sp-file $spatch_file $file
done
