structure of ftp.kernel.org, patch dirs

[Russ Fink]

Hello,

I'm a linux vet, but am relatively new to kernel compiling.  I'm trying to 
trace a nasty bug, and I wish to build incremental kernels of the 2.2 tree. 
I'm looking at ftp.kernel.org in the v2.2/testing directory, and have a 
question about the directory setup.

Can someone tell me, what is the difference between patches in the "incr" 
directory and patches in the "old" directory?

In pub/linux/kernel/v2.2/testing/incr/ I see files such as:
patch-2.2.19-pre1-pre2.gz

whereas in pub/linux/kernel/v2.2/testing/old/ I see:
patch-2.2.19-pre2.gz

My objective is to start with the latest 2.2.17 sources and patch it up to 
specific levels, e.g., 2.2.18-pre3.  Do I use patches in "incr", or patches 
in "old"?

I'm guessing that "old" patches will take me from 2.2.17 to version
2.2.18-pre-"N" without needing to go through the previous N-1 patches first, 
but that patches in "incr" will only take me from one patch level to the 
next higher level (from 1 to 2, etc).  They appear to be smaller patch 
files.  Is this right?

Thanks for your time,
Russ Fink

That would be the patch that is the diff between 2.2.19-pre1 and
2.2.19-pre2. If you already have a tree with 2.2.19-pre1, you could
apply this patch and get a tree which is 2.2.19-pre2.

That would be a patch between 2.2.19 and 2.2.19-pre2. If you had a
pristine tree with 2.2.19, you would apply this one and get a tree
with 2.2.19-pre2.

If you want to go 17->18-prex directly, use the specific patch in
'old'. If you want to go through each pre in order, use those in
'incr'.

Sounds so.
