Ok, made it compile. It seems the ./configure script is somehow
terribly broken for kernel 2.6.21. To make a long story short, to
make it compile I had to edit pvfs2-kernel.h (fastest route) and add
#define HAVE_KZALLOC 1
#define HAVE_XATTR 1
#define HAVE_POSIX_XATTR_ACL_H 1
#define HAVE_LINUX_POSIX_ACL_XATTR_H 1
#define HAVE_COMBINED_AIO_AND_VECTOR 1
#define HAVE_AIO_VFS_SUPPORT 1
#define HAVE_VFSMOUNT_GETSB 1
#define HAVE_LINUX_MOUNT_H 1
#define HAVE_PROC_HANDLER_SIX_ARG 1
It looks like configure isn't correctly defining __powerpc64__, so a
bunch of the kernel feature checks fail due to undefined errors.
Unfortunately it doesn't work to set it by hand (CFLAGS=-
D__powerpc64__), because that causes the check for aio to break. I
don't know that there's a clean workaround for this at the
moment...it seems like the powerpc64 headers in 2.6.21 aren't cleanly
defined, but maybe we just need to add the right include path.
In addition to these not being correctly set by ./configure, the
pvfs2-proc.c code uses the old
register_sysctl_table(ctl_table * table, int insert_at_head)
instead of
register_sysctl_table(ctl_table * table)
so had to fix that one too.
Yep we're aware of that one. Thanks for the report!

I'm trying to compile PVFS2 2.6.3 on a 2.6.21 kernel, both
mainstream 2.6.21 and 2.6.21 with Playstation 3 patches, but
there's a problem with kzalloc. The kzalloc thing is apparently
something that was broken in 2.6.2 and fixed in 2.6.3:
http://www.pvfs.org/fisheye/changelog/PVFS/?cs=pvfs-2-6-
branch:slang:20070315165204
However, despite that fix (which I checked is really present in
the 2.6.3 code I'm trying to compile) there is a compile error:
