Re: [PATCH v9 01/15] modpost: fix removing numeric suffixes

For now, that condition from remove_dot():

if (m && (s[n + m] == '.' || s[n + m] == 0))

which was designed to test if it's a dot or a \0 after the suffix is never satisfied. This is due to that s[n + m] always points to the last digit of a numeric suffix, not on the symbol next to it:

param_set_uint.0, s[n + m] is '0', s[n + m + 1] is '\0'

So it's off by one and was like that since 2014.

`-z uniq-symbol` linker flag which we are planning to use to

`-z unique-symbol`
