Minor nit, SOLARIS should be SPL git-svn-id: https://outreach.scidac.gov/svn/spl/trunk@17 7e1ea52c-4ff2-0310-8f11-9dd32ca42a1c

Initial commit. All spl source written up to this point wrapped in an initial reasonable autoconf style build system. This does not yet build but the configure system does appear to work properly and integrate with the kernel. Hopefully the next commit gets us back to a buildable version we can run the test suite against. git-svn-id: https://outreach.scidac.gov/svn/spl/trunk@1 7e1ea52c-4ff2-0310-8f11-9dd32ca42a1c

2.6.27+ portability changes - Added SPL_AC_3ARGS_ON_EACH_CPU configure check to determine if the older 4 argument version of on_each_cpu() should be used or the new 3 argument version. The retry argument was dropped in the new API which was never used anyway. - Updated work queue compatibility wrappers. The old way this worked was to pass a data point when initialized the workqueue. The new API assumed the work item is embedding in a structure and we us container_of() to find that data pointer. - Updated skc->skc_flags to be an unsigned long which is now type checked in the bit operations. This silences the warnings. - Updated autogen products and splat tests accordingly

Linux VM Integration Cleanup Remove all instances of functions being reimplemented in the SPL. When the prototypes are available in the linux headers but the function address itself is not exported use kallsyms_lookup_name() to find the address. The function name itself can them become a define which calls a function pointer. This is preferable to reimplementing the function in the SPL because it ensures we get the correct version of the function for the running kernel. This is actually pretty safe because the prototype is defined in the headers so we know we are calling the function properly. This patch also includes a rhel5 kernel patch we exports the needed symbols so we don't need to use kallsyms_lookup_name(). There are autoconf checks to detect if the symbol is exported and if so to use it directly. We should add patches for stock upstream kernels as needed if for no other reason than so we can easily track which additional symbols we needed exported. Those patches can also be used by anyone willing to rebuild their kernel, but this should not be a requirement. The rhel5 version of the export-symbols patch has been applied to the chaos kernel. Additional fixes: 1) Implement vmem_size() function using get_vmalloc_info() 2) SPL_CHECK_SYMBOL_EXPORT macro updated to use $LINUX_OBJ instead of $LINUX because Module.symvers is a build product. When $LINUX_OBJ != $LINUX we will not properly detect exported symbols. 3) SPL_LINUX_COMPILE_IFELSE macro updated to add include2 and $LINUX/include search paths to allow proper compilation when the kernel target build directory is not the source directory.

SLES10 Fixes (part 3): - Configure check for mutex_lock_nested(). This function was introduced as part of the mutex validator in 2.6.18, but if it's unavailable then it's safe to fallback to a plain mutex_lock().

Set cwd to '/' for the process executing insmod. Ricardo has pointed out that under Solaris the cwd is set to '/' during module load, while under Linux it is set to the callers cwd. To handle this cleanly I've reworked the module *_init()/_exit() macros so they call a *_setup()/_cleanup() function when any SPL dependent module is loaded or unloaded. This gives us a chance to perform any needed modification of the process, in this case changing the cwd. It also handily provides a way to avoid creating wrapper init()/exit() functions because the Solaris and Linux prototypes differ slightly. All dependent modules should now call the spl helper macros spl_module_{init,exit}() instead of the native linux versions. Unfortunately, it appears that under Linux there has been no consistent API in the kernel to set the cwd in a module. Because of this I have had to add more autoconf magic than I'd like. However, what I have done is correct and has been tested on RHEL5, SLES11, FC11, and CHAOS kernels. In addition, I have change the rootdir type from a 'void *' to the correct 'vnode_t *' type. And I've set rootdir to a non-NULL value.

Linux 2.6.32 compat, proc_handler() API change As of linux-2.6.32 the 'struct file *filp' argument was dropped from the proc_handle() prototype. It was apparently unused _almost_ everywhere in the kernel and this was simply cleanup. I've added a new SPL_AC_5ARGS_PROC_HANDLER autoconf check for this and the proper compat macros to correctly define the prototypes and some helper functions. It's not pretty but API compat changes rarely are.

Breaking the world for a little bit. If anyone is going to continue 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.
