Rik,
I've reviewed the patch. It's affect seems minimal and will not break NWFS as proposed -- it looks like, however, it will reduce the performance slightly of EXT2/3 with iozone for read ahead since the first section of the patch limits the read ahead window size. NWFS uses it's own read ahead underneath Linux page cache, so our performance is unaffected. I was concerned about interface issues between the FS and page cache interface. THe impact seems iminmal. I'm sorry to be on the edge of my seat, but we've got a 2.4 based Linux distribution nearly ready to go out the door, and even minor changes could push us out further.
2.4 is as solid as any release of W2K or NetWare I've seen (NetWare ships when the bug count of level II and III bugs (non-Oopes) hits 300. Microsoft ships when the bug count is under 1000.) 2.4 is way under these numbers, but since it's open source, the whole planet gets to know about every single bug, no matter how minor. I think it's ready -- I've got servers here that have been running it for weeks, and it's looking solid on everything except PCMCIA (still some problems that are Level I here) and some of the more exotic features added of late. With the DVD fixes, it's on par with W2K as is.
:-)
