Date: Fri, 8 Nov 2002 07:51:54 -0700 Bjorn/Linus, I've got a buffer-cached version of the fat32 disk working, caching for the time being only data sectors (currently it's just modified file.c, not fat.c for testing) I hadn't quite realized what a great job Linus did optimizing the routines for extremely fast sequential reading and writing, and my original design didn't handle that... Anyways, another question: currently, the creat() call does an open(...,O_WRONLY), lseeks are disallowed, and the fat chain is truncated at close time past the last cluster written. Do we want to make a distinction for the new write code so that creat() and open(...,O_WRONLY) act differently, that is, open(...,O_WRONLY) allows seeking and appending to end-of-file? This would allow logfiles, etc to be written, which can't be handled now.
