Analyze and fix the following issue in the Linux kernel code: [IPCOMP]: Fix truesize after decompression
Problem Details: The truesize check has uncovered the fact that we forgot to update truesize after pskb_expand_head. Unfortunately pskb_expand_head can't update it for us because it's used in all sorts of different contexts, some of which would not allow truesize to be updated by itself. So the solution for now is to...
