[Pvfs2-users] Segmentation fault on insmod pvfs2.ko (pvfs2.6.3-patched, kernel 2.6.22-rc4)

[Murali Vilayannur]

Hi pete,
Agreed. What I meant to say was that the kmem_cache_create interface
may be deprecated soon. Instead of phasing out an argument, a BUG() in
the kernel ensures that 3rd party folks such as us fix this issue
before the actual release of the 2.6.22 kernel.
How about the following patch? I have only compile tested it and made
sure that it loads on my machine. But I don't run the latest kernels
and so that is not such a good test..:)
thanks,
Murali
