net/ipv4 currently contains around 100 source files containing the IP implementation and lots of other functionality (UDP, TCP, xfrm, etc.)
# 1/3 To make the networking source tree more self documenting and well structured 1/3 moves the 30 shared TCP source files to a own subdirectory of net/ipv4/. # 2/3 A huge part of the TCP code is congestion control algorithms. With the same goal as above, this moves the cc algos to a own subdirectory of net/ipv4/tcp/ # 3/3 Implementation of a suggestion of valdis, to have a new directory net/ipv4v6_shared that contains all the code shared between IPv4 and IPv6. This creates net/ipv4v6_shared and moves the net/ipv4/tcp directory of shared TCP code there. While every commit depends on its previous commits, it is also possible and sensible to only apply (1) or (1,2) , depending on how conservative one wants to decide regarding directory structure changes.
