How to verify sht-ops-conversion patch doesn't change anything

[Tejun Heo <htejun@gmail.com>]

The fifth and sixth patch, cleanup-sht and cleanup-ops, can be
verified not to change the final sht and ops by printing out all
entries and comparing the values before and after.

1. Get the following git branch.

   http://git.kernel.org/?p=linux/kernel/git/tj/libata-dev.git;a=shortlog;h=cleanup-sht-ops-verify-before
   git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata-dev.git cleanup-sht-ops-verify-before

   Build the kernel with the libata modules to verify and run the
   following command.

   # insmod libata.ko; for i in $(ls *.ko | sort | grep -v libata.ko); do insmod $i; done; dmesg -c | grep -E 'SHT|OPS' | sed -r 's/^\[[ \.0-9]*\] (.*)$/\1/' | sort > ~/out.before

   If you need some libata modules built-in for rootfs, it's okay too.
   It will give the same result.

2. Get the following git branch.

   http://git.kernel.org/?p=linux/kernel/git/tj/libata-dev.git;a=shortlog;h=cleanup-sht-ops-verify-after
   git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata-dev.git cleanup-sht-ops-verify-after

   # insmod libata.ko; for i in $(ls *.ko | sort | grep -v libata.ko); do insmod $i; done; dmesg -c | grep -E 'SHT|OPS' | sed -r 's/^\[[ \.0-9]*\] (.*)$/\1/' | sort > ~/out.after

3. Use your favorite diff program to compare out.before and out.after.
   Graphical ones which show in-line differences will work best.

Thanks.
