Report - fixes needed

["Kirk Alexander" <kirkalx@yahoo.co.nz>]

I've done some grep'ing for some possible fixes required in 2.5.1 (final).
The problems are:
 - changing of member cmd in 'struct request' to a char array from int
 - changing of blk_init_queue() to take 3 args not 2
 - use of the removed member b_reqnext in 'struct buffer_head'

Note there are probably some files I have missed due to not thinking generally
enough and there will be false matches also. As you can probably tell from the
below I'm definitely not a grep wizard so if someone can think of a way to
search for code like

	printk(" ...  %d  ... ", ..., rq->cmd, ...);

that will turn up more things in need of fixing.

Sorry if this info has already been found - I couldn't find an overall report
like this in the archives.


1)
Look for possible invalid use of altered member cmd from struct request
- search for this kind of thing

		switch (rq->cmd)
		{
			case READ:
		...

grep "switch[[:space:]]*([a-zA-Z0-9_]*->cmd[[:space:]]*)"
grep "switch[[:space:]]*([a-zA-Z0-9_]*\.cmd[[:space:]]*)"
 then filter on
grep "struct[[:space:]]*request[[:space:]]"

2)
Look for possible invalid use of altered member cmd from struct request
- search for this kind of thing

	if (rq->cmd == READ) {
		...

  and

	rq->cmd = READ;

grep -- "->cmd[[:space:]]*="
 then filter on
grep "struct[[:space:]]*request[[:space:]]"
