[PVFS-users] Question regarding include/modules *.stamp/*.ver files for pvfs

[Michael Homa]

Hi.

Am upgrading the linux kernel on our cluster system. I have two kernels
that I can upgrade to:
  o RH 2.4.20.28.7, and
  o RH 2.4.20.28.9

I had no problems compiling pvfs version 1.6.0 under 2.4.20.28.7. When I
compiled the same version of pvfs for 2.4.20.28.9, I encountered the
following make error:

make: *** No rule to make target `/usr/src/linux/include/linux/modules/
  af_netlink.ver', needed by `pvfs_mod.o'.

A key difference between the two directories:

   /usr/src/linux-2.4.20.28.7/include/linux/modules/
     and
   /usr/src/linux-2.4.20.28.9/include/linux/modules/

is the absence of the two files, af_netlink.stamp and af_netlink_ver, in
the later subtree.

I've searched the web on information regarding the function and layout of
*.stamp and *.ver files. If info is available, it's not readily available
or easily found. Does anyone have information on these types of files?

In the 2.4.20.28 subtree, the two relevant files are:
  -rw-r--r--    1 root     root            0 Dec 18  2003 af_netlink.stamp
  -rw-r--r--    1 root     root            1 Dec 18  2003 af_netlink.ver

Obviously, I can create the two files in the 2.4.20.28.9 subtree or copy
them from the *.7 subtree. But, it would be nice to know the
ramifications, if any, of doing so. Any info is appreciated. Thanks.
