[PATCH v4 2/8] scripts/kallsyms: ensure that all possible combinations are compressed

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



For a symbol, there may be more than one place that can be merged. For
example: nfs_fs_proc_net_init, there are two "f"+"s_" combinations.
And we're only compressing the first combination at the moment. Let's
compress all possible combinations.
