[Pvfs2-users] Re: pvsf2.6.3 and kzalloc detect broken in kernel 2.6.21?

[Jan Wagner]

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

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.

I'm trying to compile PVFS2 2.6.3 on a 2.6.21 kernel, both mainstream 2.6.21

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:
