RCU is a synchronization mechanism that was added to the Linux kernel
during the 2.5 development effort that is optimized for read-mostly
situations. Although RCU is actually quite simple once you understand it,
getting there can sometimes be a challenge. Part of the problem is that
most of the past descriptions of RCU have been written with the mistaken
assumption that there is "one true way" to describe RCU. Instead,
the experience has been that different people must take different paths
to arrive at an understanding of RCU.

Это, видимо, итоги многочисленных попыток объяснить большому количеству малограмотных конкретную реализацию поддержки RCU. IMHO имело смысл начать с общего описания механизма (ну хотя бы отсюда взять можно было), а потом уже объяснить особенности конкретной реализации. Но данные конкретные "ядерные" люди, видимо, не могут уже объяснять идею "вообще", а только в привязке к данной реализации :)

And the LORD spake, saying, "First shalt thou take out the Holy Pin, then shalt thou count to three, no more, no less. Three shall be the number thou shalt count, and the number of the counting shall be three. Four shalt thou not count, neither count thou two, excepting that thou then proceed to three. Five is right out. Once the number three, being the third number, be reached, then lobbest thou thy Holy Hand Grenade of Antioch towards thy foe, who being naughty in My sight, shall snuff it."
