It is not a what it is a who, called Linus. Hans Reiser mounted a major
campaign over several months to get into the kernel, and it took a while
after that to get the bugs out. There are mumblings about ext3, but it does
make quite a lot of mainline kernel changes I am told, so I would not be
so sure - except for the fact that Redhat appears to be going to make it
their default filesystem.
As for us, there have been efforts, which met with zero response from Linus
to get XFS into the kernel. Various folks then told us - wait for 2.5 and
then backport from there. In the meantime I have about 3 million other
things to do at the moment which are not even to do with Linux, and do not
have the time to continually bombard Linus with patches. One other reason
XFS is harder to get in is that we have some code in the middle of the VM
system to deal with delayed allocate pages, and if you follow Linux kernel
development you will realize that the VM has been rewritten several times
over the last few months, it is not the most stable thing in the world.
Item 3 million and one on my list right now is getting the latest VM
rewrite and XFS to talk to each other (no it is not bottom of the list,
but you try doing major surgery on two operating systems at once and
staying sane).
At the moment an effort is under way to merge the XFS acl interface with
the ext2 acl interface so we can get a system call - Linus will not accept
more than one interface in this area. Once this is done then our intrusions
into the mainline kernel will be smaller and we can try again. This will
also make it easier for distributions to include XFS - we appear to be
in the latest Mandrake release by the way.
