working on this branch for the next few days I suggested you work off of the 0.3.1 tag. The following changes are fairly extensive and are designed to make the SPL compatible with all kernels in the range of 2.6.18-2.6.25. There were 13 relevant API changes between these releases and I have added the needed autoconf tests to check for them. However, this has not all been tested extensively. I'll sort of the breakage on Fedora Core 9 and RHEL5 this week. SPL_AC_TYPE_UINTPTR_T SPL_AC_TYPE_KMEM_CACHE_T SPL_AC_KMEM_CACHE_DESTROY_INT SPL_AC_ATOMIC_PANIC_NOTIFIER SPL_AC_3ARGS_INIT_WORK SPL_AC_2ARGS_REGISTER_SYSCTL SPL_AC_KMEM_CACHE_T SPL_AC_KMEM_CACHE_CREATE_DTOR SPL_AC_3ARG_KMEM_CACHE_CREATE_CTOR SPL_AC_SET_SHRINKER SPL_AC_PATH_IN_NAMEIDATA SPL_AC_TASK_CURR SPL_AC_CTL_UNNUMBERED git-svn-id: https://outreach.scidac.gov/svn/spl/trunk@119 7e1ea52c-4ff2-0310-8f11-9dd32ca42a1c
