/* Heavily-used const UNICODE_STRINGs are defined here once. The idea is a

speed improvement by not having to initialize a UNICODE_STRING every time

we make a string comparison. The strings are not defined as const,
|
|
because the respective NT functions are not taking const arguments

and doing so here results in lots of extra casts for no good reason.

Rather, the strings are placed in the R/O section .rdata, so we get

a SEGV if some code erroneously tries to overwrite these strings. */
