That's great! Do you mean removal from Linux?

Feature removal txt file was removed from the kernel so there is no
"schedule" per se, not sure what the process these days is for driver
removal. How about punting it to staging for a release or two and then
remove it? Not sure if that would be frowned upon or welcomed. That
would have the cost of moving history through directories but git
--follow helps with that these days. The gain of moving it to staging
IMHO would be that if anyone who might care would need to complain may
do so for a directory change for 1-2 release may spot this easily and
the issues would be much less than an immediate removal.

That is the process for driver removal, so of course it is welcomed :)

Yes, that's why we do it this way.

Mike, feel free to send me a patch for this if you want me to queue it
up for 4.3.  For 4.2 it's too late.

Greg, how would you like to consume that patch? There are a number of large
files. We can break things up into a series and send through email. We could
also post a repo somewhere that you can do a pull from. Something else?

Thanks

If you use -M to 'git format-patch' when generating a patch, it will
show that you just moved the files around the directory tree, and the
patch should be quite small and easy to email and review.

In fact, you should use that as a default for all patches, as it's now a
standard that normal patch can use to consume, I have this in my
.gitalias file:
	[alias]
		fp = format-patch -M

and just use 'git fp' all the time.

try that and see what the results are.

thanks,

And if you still want to use default regular commands then you can use:

[diff]
        renamelimit=0

Actually this is to help trigger rename detection to be a bit more
greedy, you still need -M.
