Qsort_r

FreeBSD 14 确定延期

原定4月25日开始的code slush和KBI冻结并未发生，主要的原因是 OpenSSL 3.0 还未合并， 以及 OpenZFS 近期的一些可靠性问题。

其中，OpenSSL 3.0 由于对 API 的改动比较大，因此会导致一些 port 无法正常工作 （PR 258413）。 近期已经有一批 port 标记为与 OpenSSL 3.x 不兼容， 不过修掉这些可能会需要不少时间。

Moving toward a standarized qsort_r(3)

History of qsort_r(3)

First introduced in Research Unix V3 and eventually standardized as part of C Standard Library as of ANSI/ISO C89, qsort(3) provided an abstract interface where programmers can perform sort operation over an array of objects, by supplying a pointer to that array, the total number of the member objects, the size of individual member object, as well as a compare function. The compare function is expected to take two parameters, both pointers to a member object, and it shall return a negative number, 0, or a positive number, if the first object is considered smaller, equal, or greater respectively.
