[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.
