Description:
As the end of the 1990s approached, a lot of kernel-development effort was going into improving support for 32-bit systems with shockingly large amounts of memory installed. This being the 1990s,
having more than 1GB of memory in such a system was deemed to be shocking.
Many of the compromises made to support such inconceivably large systems
have remained in the kernel to this day. One of those compromises
bounce buffering of I/O requests in the block layer has finally been
eased out for the 6.16 release, more than a quarter-century after its introduction.
