Hmm, are you saying that there are no changes to the VM code that is in the
Linux kernel by XFS patches?

Good question. I don't know where the src rpms come from...I'll ask my
colleagues where they got the ones we are using/testing at the moment.
FYI, I filed this in hopes of getting a kernel that does not have security/data
losing/instability problems and has better performance. Stock Linux kernels
don't cut it. The RH line of kernels are usually meeting these requirements.
The RH 2.4.20-13 kernel (with whatever XFS patches my colleagues found) had
major improvements over the plain RH 2.4.20-13 in some cases. I just noticed
that the new mail server we put up with a RH 7.3 installation and a XFS patched
kernel (RH 2.4.20-13) exhibited the swapping behaviour we found with loaded
boxes that just had plain RH 2.4.20-13/18 kernels. Only less servere swapping
than what I saw with plain RH 2.4.20-xx kernels.
So if there are no VM code changes by the XFS patches (likely 1.2) then just
close this 'bug'. If there are, then maybe you guys would like to look into
this since you have the knowledge and understanding needed to work on VM code
in the Linux kernel.
